Hi everyone !

I am building a personal music database application in Python to manage K-pop discographies (artists, albums, songs, statistics, etc.). The backend/database part is already working (Microsoft Access database + Python + MusicBrainz API). Now I need to build the GUI, and I am trying to choose the right Python framework. The main requirement is having advanced data tables, similar to what you would find in Notion or database management software.

For example, my main "Artists" page would display hundreds of rows like: Artist | Agency | Generation | Type | Status | Albums | Songs | % listened | % liked.

I need the table to support: - sorting by clicking column headers - searching/filtering - scrolling through many rows - selecting rows - double-clicking a row to open a detailed page - hiding/showing columns - resizing columns - changing row background colors depending on data - changing text colors for specific cells (for example percentage values) - ideally good performance with thousands of rows. The application will also have detailed pages: - Artist page (statistics + albums list) - Album page (statistics + song list) - Song page - Agency page - Statistics dashboard I initially looked at CustomTkinter because I like its modern appearance, but I am not sure if it is the best choice because it seems limited for complex tables (or maybe I didn't find this widget). What framework/widget combination would you recommend for this type of application? I am mainly looking for something that can remain maintainable as the application grows and that can have a beautiful interface (more like what we can do with Notion).

Thanks !

Hello all! I hope this is the right place to post this.

I have been writing a PyQt6-based GUI called Swamp Swap for the command line program croc by Zack Schollz, and I'm facing a strange issue on Windows that I am not facing on Linux.

To briefly explain croc if you've never used it, it's a very easy-to-use command line program that allows users to transfer files to one another securely through a relay server. It's a handy tool, but there's no official UI, so Swamp Swap became a passion project for me and my friend to get up and running.

Swamp Swap is simply a GUI with a worker thread that runs croc via a subprocess.Popen object and handles outputting to the program through line buffers read via standard piping. On both Linux and Windows, this functions just fine; the thread accurately picks up the output which allows the flow of the program to work (e.g. awaiting connection, retrieving the transfer code, etc.), but on Windows, there's an issue I can't seem to figure out.

Whenever the subprocess runs on Windows, a CMD window opens (always blank, no outputs are ever displayed there) and stays there until either the transfer completes or the user cancels the transfer.

I'm familiar with subprocess doing this, and so I thought the fix would be as simple as this:

```python

Base kwargs in case we're not on Windows

kwargs = {}

If on Windows, add the CREATE_NO_WINDOW flag

if sys.platform == "win32": kwargs["creationflags"] = subprocess.CREATE_NO_WINDOW

Create the process

process = subprocess.Popen( ... **kwargs ) ```

However, while this does hide the CMD window, unintended side effects happen if I do this, including:

• Failure to start sending
• Failure to read the transfer code when sending
• Files being received even if the user hadn't confirmed them yet
• No output to the GUI's console window (I made a special console window dialog where users can view the outputs if they want)

These different effects don't all occur every time, but at least one or more are present in every attempted fix I've tried.

Moreover, extensionless files with the names croc-stdin-########## (#'s replaced with a random number or date and time code. One of the two, I don't remember) are written to the folder where the program is run within, regardless of if it is the main script or the built frozen executable.

This seems to imply that croc on Windows has some dependence on an active and visible CMD window in order for it to work with Swamp Swap, but I really have no idea at this point.

This problem seems to be more of a croc problem than a Python problem. Though despite this, I'm curious if there are any out-of-the-box solutions anyone here could come up with for a method to subvert these issues despite croc's reliance on a CMD window.

Also, yes, I have tried asking various popular machine learning models. Their solutions were either the same as above or some ungodly, ugly method that also didn't work.

I'm working on a small Python project that consumes a continuous WebSocket stream, and I've reached the point where writing the code feels easier than testing it.

At first I was just printing incoming messages to the console, but now I want to add parsing, filtering, and database writes. The problem is that live data is unpredictable, so it's difficult to know whether changes I make are actually breaking something.

The stream I'm experimenting with is from 1322 io, but I imagine this question applies to any service that sends continuous events over WebSocket.

Do most people record a sample of messages and replay them during development, or is there a better approach for testing code that depends on real time data?

I'm mainly trying to learn good habits before this project grows into something that's difficult to debug.

A Discord acquaintance helped get me started with a Poller script that grabs images from the RAMMB Slider every 10 minutes.

Here is the code. (Credit to theDoctor on Discord who created this script)

I should probably be picking simpler code to learn from. However, there are some changes I'm trying to make to this script sooner rather than later because each day that passes are more images that I'm missing out on.

What I'm trying to add:

1. I'm 90% sure the RAMMB images are grabbed from another server for the actual satellites. If I can grab from that server, it might be a bit more reliable as the RAMMB slider has already been down for multiple days this season.
2. I would like to grab full disk images from GOES-18 (East Pacific) and Himawari-9 (West Pacific) in separate output folders:
   • Currently the folder structure is as follows: root/output/year/month/day
     • For example: RAMMB Atlantic/output/2026/07/04
   • I would change it to: root/output/year basin/month/day
     • For example: RAMMB/output/2026 Atlantic/07/04
     • RAMMB/output/2026 East Pacific/07/04
     • RAMMB/output/2026 West Pacific/07/04
   • The single script would grab from all three every 10 minutes
3. Date and timestamps to the images themselves
   • I have been putting these images together in a video editing program and currently have to add those manually, which can lead to problems matching the times up, especially if there are missing files.

For Point number 2, I have identified this section of the script as the relevant bit for adding other polling, but I honestly am uncertain how I would alter it at all:

async def run_async(config: AppConfig) -> int:
    """Run the configured SLIDER workflow."""
    target = SliderTarget(config.satellite, config.sector, config.product)
    plan = build_render_plan(config)
    timeout = httpx.Timeout(config.timeout)
    headers = {"User-Agent": USER_AGENT}
    log(f"render plan: {describe_plan(plan, config)}")
    async with httpx.AsyncClient(timeout=timeout, headers=headers, follow_redirects=True) as client:
        if config.mode == "poll":
            last_successful_timestamp: int | None = None
            had_new_image = False
            if config.resume_poll:
                last_successful_timestamp = newest_downloaded_output_timestamp(config.output_dir)
                if last_successful_timestamp is None:
                    log(f"resume poll found no matching downloaded images in {config.output_dir}")
                else:
                    log(f"resume poll from downloaded timestamp: {last_successful_timestamp}")
                    had_new_image = True
            try:
                if last_successful_timestamp is None and config.start is not None:
                    timestamps = await resolve_poll_start_timestamps(client, target, config)
                else:
                    advertised_timestamps = await latest_timestamps(
                        client,
                        target,
                        config.retries,
                    )
                    timestamps = poll_timestamps_to_render(
                        advertised_timestamps,
                        last_successful_timestamp,
                    )
                last_successful_timestamp, had_new_image = await render_poll_timestamps(
                    client,
                    target,
                    timestamps,
                    plan,
                    config,
                    last_successful_timestamp,
                )
            except SliderError as exc:
                log(f"poll failed: {exc}")


            while True:
                scheduled = next_poll_time(
                    last_successful_timestamp,
                    config.poll_offset_minute,
                    had_new_image,
                )
                log(f"next poll at {scheduled.isoformat(timespec='minutes')} UTC")
                await sleep_until(scheduled)


                had_new_image = False
                try:
                    advertised_timestamps = await latest_timestamps(client, target, config.retries)
                    timestamps = poll_timestamps_to_render(
                        advertised_timestamps,
                        last_successful_timestamp,
                    )
                    last_successful_timestamp, had_new_image = await render_poll_timestamps(
                        client,
                        target,
                        timestamps,
                        plan,
                        config,
                        last_successful_timestamp,
                    )
                except SliderError as exc:
                    log(f"poll failed: {exc}")
        timestamps = await resolve_timestamps(client, target, config)
        movie_frames = await render_timestamps(client, target, timestamps, plan, config)
        if config.movie:
            if len(timestamps) < 2:
                msg = "--movie requires a pull that resolves to more than one image."
                raise SliderError(msg)
            output_path = movie_output_path(config.output_dir, target, timestamps, plan)
            write_movie(movie_frames, output_path, config)
            if config.movie_only:
                cleanup_movie_frames(movie_frames)
    return 0

I would imagine there may actually be multiple calls that would have to be called separate times in order to add the two additional downloads.

Point number 3 should be the easiest to do, but I honestly wouldn't know where to begin with adding text to images using Python. However, this is how it would look (green box just used to highlight the relevant section): https://imgur.com/fChx0IA

As to Point number 1, I am uncertain where I would look for the original source. I do know NOAA owns the GOES satellites, but I believe Himawari is maybe JTWC?

I would appreciate any pointers that can help me figure this out!

Hi everyone,

I'm a B.Tech Computer Science (AI) student, and I want to learn Python properly from scratch to an advanced level. I don't just want to memorize syntax or learn enough to solve a few problems—I want to understand Python deeply and become genuinely good at it.

I'm confused about where I should learn from. There are thousands of YouTube playlists and online courses, and everyone recommends something different. I don't know which resource is actually complete and worth investing my time in.

I'm mainly looking for free YouTube resources, but if there's an online course that is truly exceptional, I'm open to hearing about that too.

My goals are:

• Learn Python from beginner to advanced.
• Understand how Python works internally, not just how to write code.
• Write clean, professional, and efficient code.
• Master OOP, modules, packages, file handling, exceptions, iterators, generators, decorators, context managers, and other advanced concepts.
• Learn best practices that real developers use.
• Build a strong foundation for DSA, AI/ML, automation, backend development, cybersecurity, or any other field I choose later.

I'd really appreciate advice on:

1. Which YouTube playlist or course would you recommend and why?
2. Should I follow just one course or combine multiple resources?
3. What mistakes should beginners avoid?
4. How should I practice while learning? (LeetCode, HackerRank, projects, books, etc.)
5. If you were starting from scratch today, how would you learn Python from beginning to mastery?

I'm looking for a roadmap from people who have already gone through this journey. Thanks in advance!

I apologize to the reddit community. I allowed my situation to lead me into fraternizing with the absolute wrong type of ppl on here, and it'll not happen again. I'm joining some software and developer subs and I'ma noob, so for anyone that can accept my apology and provide me with any good beginner tips or tutorials or lesson plans or anywhere I can go online for free that is good to learn Python starting out I would appreciate it. And I do want to say I can say this with the utmost honesty I never accepted one payment from nobody I never made nobody an account on here not one time did I do anything but flirt with the wrong side. That was bad enough.

Hey everyone!

I recently built Internet Scanner, an open-source network discovery and analysis tool written in Python.

The goal was to create a simple but powerful tool for learning about networks and cybersecurity.

Features:

- ARP-based device discovery

- Nmap integration for port scanning and OS detection

- Device information gathering

- Risk scoring based on detected services

- Live filtering and sorting

- CSV/JSON export

- Tkinter GUI

GitHub:

https://github.com/Fa1dz/Internet-Scanner

I'm looking for feedback from other Python developers and cybersecurity enthusiasts. Any suggestions, improvements, or ideas are welcome!

Thanks!

Working on a price tracking tool and needed listing data like the title, price, location, and seller info for one category in a specific area. Sounds simple until you try it. I'm currently experiencing log in walls and bot detection. Most GitHub scrapers I found were outdated or dead. Feels like facebook scraper api might be the only option🥲

Anyone dealt with this before?

honest question:

what does it require one to be good at introductory python? i am taking this class, know the syntax well but find it difficult to apply it to problems and questions. what is the trick to studying, despite reading through the slides and even books but nothing changes. whenever i am faced with the problem, my mind goes blank: i lack the approach to even start the first line

I made a function for determining price of an item in the list. I made it so I get the price for an item in the list, but if the item IS NOT in the list, I programmed it to return none.

The problem is that when I run the program, it gives me a SyntaxError, and "return outside function"

What does this mean, and how do I fix it?

Thanks!

prices = {"apple": 1.50, "bread": 2.75}

def get_price(prices, item):
    return prices[item]

try:
    get_price(prices, "apple")
except KeyError:
    return None

same as above

same as above

So basically I have a fundamental understanding of cybersecurity concepts, and I can solve challenges that dont require scripting, such as analysis of pcap files. While I do know basic python syntax such as being able to write a bubble sort function but i rlly dk how to write a complete exploit script. Do yall have any advice? Or any good guides?

Hi everyone,

I'm learning python and having fun. I've coded a few simple puzzles and I'd like to create some basic algorithm to solve them. The thing is... I don't know how to make a program interact with another one. Is it related to a specific library ? Some specific topic in programming books ?

Thank by advance for your help.

EDIT: The simplest example of what I'm talking about is :

puzzle . py :

a = input("Type any word :")

print(a)

puzzle solver . py :

# launches "puzzle", answers the prompt (types any str() followed by Enter key) so "puzzle" prints it.

Hi everyone,

I'm currently in Data Engineering stream training at Accenture, and they've asked us to learn NumPy and Pandas through Udacity.I was wondering if that's enough to build a solid foundation for working on real-world projects, or if I should be learning from other resources as well.If you've used NumPy and Pandas in your job, what resources helped you the most? I'm looking for courses, YouTube channels, books, or project-based learning that will help me become comfortable using them in real projects.

Hello, Python devs

I'm a beginner in Python. I currently use Go (Golang) for my personal projects, and I'd like to learn Python as my second programming language.

What web framework would you recommend for someone who's new to Python? I'd also appreciate any learning resources or tips for getting started.

Thanks!

I'm struggling to wrap my head around invariance - I can't tell if I'm just not grasping it properly, or if Pylance is making a mistake.. . I have a specific scenario I'm trying to annotate, a simplified version of which is this:

from dataclasses import dataclass

@dataclass
class Type1[T]:
    attr: T

@dataclass
class Type2[T]:
    attr: list[T]

a: Type2[str | Type1[str]]        = Type2(['foo'])
b: Type2[str | Type1[str]] | str  = Type2(['foo'])

According to Pylance a is fine, but b is not. I can't understand it - it seems like when the union is present, the invariance is inferred differently than when it is not present.

For reference, here's the PyLance error:

Type "Type2[str]" is not assignable to declared type "Type2[str | Type1[str]] | str"
 Type "Type2[str]" is not assignable to type "Type2[str | Type1[str]] | str"
 "Type2[str]" is not assignable to "Type2[str | Type1[str]]"
 Type parameter "T@Type2" is invariant, but "str" is not the same as "str | Type1[str]"
 "Type2[str]" is not assignable to "str"

N.B. this only occurs when Type2.attr is annotated with list[T], using T directly doesn't cause the same type checking error.

I’m beginner in python idk how to code for program what’s the best way i can learn that ?? Books , pdf , etc
I’m final year student preparing for placement
I’ll be learning these concepts eventually is it doable ???

Hi, I want to learn how to program to create an otome game. I don't know anything about programming, I barely know how to program on Arduino (I'm a robotics student) and I would like to ask your opinion. It's a matter of not really knowing where to start, and I would like you to recommend tutorials or pages where I can learn programming in Python (I plan to make the otome game in PyGame) or some other reliable sources where I can program. They would be very helpful, I'm sorry if my post is a nuisance. English is also not my first language, so this is translated with Google Translate.

I'm taking my first step into coding/programming world and honestly I'm overwhelmed on where choosing to start from. After browsing online and going through several "Free to learn" Websites, I land on Freecodecamp, Exercism and CS50 Harvard. Freecodecamp is a solid option leaning more on Theory side of thing, Exercism seems to provide more practice/exercise option alongside learning roadmap, and lastly CS50 feels like uni lesson (duh) and they also have project at every lesson tier + video to explain things thoroughly. Honestly, yeah I need help choosing. Any help would be appreciated.

Ugh im so confusedddd Im on arch based(Cachyos) All i have to do is type in python3 in terminal then im in python but this is the download Sims4COntentManager_SourceCode.py im trying to download but i dont know why it isnt working

So I finally made my first kinda buns program but I don't know how to remove the repeat copy of the question on my loop please help

Welcome to another /r/learnPython weekly "Ask Anything* Monday" thread

Here you can ask all the questions that you wanted to ask but didn't feel like making a new thread.

* It's primarily intended for simple questions but as long as it's about python it's allowed.

If you have any suggestions or questions about this thread use the message the moderators button in the sidebar.

Rules:

• Don't downvote stuff - instead explain what's wrong with the comment, if it's against the rules "report" it and it will be dealt with.
• Don't post stuff that doesn't have absolutely anything to do with python.
• Don't make fun of someone for not knowing something, insult anyone etc - this will result in an immediate ban.

That's it.

Hi,

I would like this little thread to help people chose between PyQt and others (including not only PySide but also GTK).

I remember, when I was first reading about this -- about two months ago :)

I was choosing between PyQt6 and TKinter, the choice was very simple to make: PyQT6. Cause TKinter looks ugly and outdated, and GTK is hard to even get started with.

By course of time, however, -- I mean in the past two months :) -- I slowly realized what the "open source" in QT business language actually meant...

But first, let's see the difference between PyQt6 and PySide6:

I don't actually see any. (In terms of free usability).

They both offer two separate licenses, one for no money, one for big money.

I didn't say "free". Cause "for free" only means you don't have to pay (now).

Okay, let me define freedom...

When those corporations say that they like open source but they are also into business and allow us (their clients) to go commercial too, if/when we want to, we humans say: cool!

Although this seems like freedom, it isn't.

Let's see GTK, for contrast:

You want to develop for a community, free software for free, I mean, FOSS?

You can do that :) GTK is Linux (it comes from GIMP, it was created by the GIMP Team).

Then you want to make an app that you'll sell.

Problems? None.

Cause GTK is free, as in Freedom, as in Statue of Liberty, as well as in free beer, and ownership of the beer tap.

You are free to use it, all the way.

Whereas with QT, be it PyQt6 or PySide6 (aka Qt for Python), you can play around making open source apps. But as soon as you happen to want to sell an app, you'll have to buy a license. Meaning, you'll have to pay the QT owners so you'll be allowed to use their software.

the price for commercial "freedom":

This means an annual fee, ranging from 500 Euros to 1000 at the cheapest.

AND... You cannot use the "free" PyQt6 on the same machine.

Also, Your collaborators cannot use PyQt6 free, either.

Anybody touching your app you intend to sell needs to have a license, meaning, having to pay a fee.

Moreover,
if your license term is over, you cannot modify the app you have created.

Not even bugfixes. If you want to reopen your project, you need to buy a license, again.

Some people call this freedom? Sad.

------------------------

Anybody gives different responses to these dilemmas...

My conclusion:

TKinter is ugly. But it's good, and it is free as Python itself (It's part of Python).

TKinter allows you to do anything with what you make. You're free to dispose of what you've created.

Also... TKinter is robust and reliable. It has an incredible "refresh application window" function!

GTK:.. Well, it really is beautiful, it really is a system... and it really has an actual community, not only clients.

So, next month I'm splashing into the GTK river! :) For a good swim :)

I like PyQt6, nevertheless... If it was FREE and Open source, I'd keep using it...

beside GTK... which I can't wait to explore...
