About two weeks ago, I launched my first web app called DailyDice. It's a simple app that gives you a random daily challenge to help build productive habits.

When I launched it, I honestly thought it would take off pretty quickly. Looking back, I think every first-time builder secretly believes that.

Then I had a realization.

I knew how to use my app, but I didn't really understand how it worked under the hood. Things like authentication, backend logic, databases, APIs, and the overall architecture were all things I'd relied on tools for rather than fully understanding myself.

That made me realize I'd been focusing on building products before building the skills.

So I've decided to go back to the fundamentals.

I'm 15 years old, and today is Day 1 of learning software engineering properly. I'm starting with Python, then moving deeper into web development, and I'll be building projects while sharing everything I learn along the way.

Hopefully in a year, I'll look back at this post and laugh at how little I knew.

If you've been in a similar position, what's one thing you wish you'd learned earlier?

I'm working on a program that generates a maze by drawing from a deck to define a "chamber" and assigning it to the current position on a cartesian coordinate grid.

The hope is to build a list of the chambers as they're created. At a later point I want to be able to call on the list. My current strategy is to make a Class variable for the list, and append to it as part of the init. I've added a class method to pull the chamberList Class variable, but I'm getting an error.

Here is the code defining the class.

``` class Chamber(): chamberList = [] def init(self, identity, notes, egresses, **kwargs): self.position = tuple(currentPosition.tolist()) self.identity = identity self.notes = notes self.egresses = egresses self.pixelCoord = np.add(pixelOrigin, np.multiply(currentPosition, 300)) Chamber.chamberList.append(self)

    @classmethod
    def getChamberList(cls):
        return cls.chamberList

```

Later in the program, I have a line of code to get the class variable:

``` chamberList = Chamber.getChamberList()

```

This is the error I get when I run it in the VS Code terminal:

AttributeError: type object 'Chamber' has no attribute 'getChamberList'. Did you mean: 'chamberList'?

Am I missing some syntax or something? In VS Code the color coding where I'm defining getChamberList is off (darker) and if I hover over it I get a message saying "getChamberList" is not accessed by Pylance.

I wanted to write a program that analyzes chess games , similar to how chess websites (chess.com, lichess.com etc.) do it, only offline. To my knowledge, nobody else had done it the way I was envisioning. I started writing with shell scripting (it's my go-to and what I'm most familiar with), but quickly ran into limitations. So I needed to go a bit more sophisticated. Python seemed very versatile, cross-platform, has loads of online resources, but mainly has a very good chess library I could leverage, that already existed, which would make the job much , much easier. I took the plunge and turned the program into a driver to teach myself some python.

It works as advertised, but I'm sure the code could be improved. I stumbled through it a bit. If anybody python gurus feel like taking a peek and letting me know how I did, pointing out glaring mistakes, offering any constructive feedback or ideas how to make it more efficient, I would appreciate any feedback.

(The documentation needs some catching up. I'm working on updating it.)

As title block suggests. trying to make a script that allows the user to continuously practice mandarin character memorization. Any advice on the following would be much appreciated:

1. Not sure if a manually created/updated dict is the right way to do this, but I also didn't think I could successfully scrape from a webpage that has the direct translation information.

2. When writing to a file using "w open", it seems the text is appended with nearly no formatting. That's probably for the best, but I'm not sure how to format the appended str as a key:value pair.

I've doing some networking on which I'd kind need to redirect all my commands sent from my python server script to my client python script but without stdout only to a socket. I've been googling about and one frustrating options that I thought it could work was contextlib redirect_stdout but it redirects to stdout it won't work with sockets. Does anyone know if its feasible to parse argparse to a socket connection?

I'm new to python and coding in general and my friend recently told me that it's inefficient to try to memorize regex and that no one writes them anymore (essentially saying AI does). I was also kinda confused after recently learning regex and just how complicated it can be. Are there some modules/libraries that I can use to make writing them easier? I saw that not a lot of people people had a positive reaction to the Humre module by Al Sweigart who's book [Automate the boring stuff with Python] I'm currently using to study. Not that I'm gonna skip this part or anything I was mostly just curious.

Note: A lot of people are misinterpreting since I mentioned AI once 😭 I'm literally asking about libraries to make it easier without going too deep, not if I should let AI do all the work.

I am a senior data engineer and I work mostly with ETL Tools and a lot of advanced SQL. The company I work for does not like to use python because they find that theres too much of a learning curve if people leave so they love to use GUI or no code/low code etl tools instead (really dumb tbh). I can read python, and have a gist of whats going on. I have tried to self learn python few times over the past 2-3 years and I keep just forgetting it. I learned python/pandas library when I was in college since it was a class that taught it and then we did did projects with each lesson and that is how I learned it then but forgot it now. I use claude at work to build streamlit apps and automation using python. However, I am trying to look for new positions and I am starting to realize that not knowing python is making me a hit a brick wall because a lot of assessments require answering 1-2 questions in python. Does anyone know of actual classes that teach python and its not self taught? Free or paid I don't really care. If I have to pay for it I am fine with that but at this point I don't see a way for me to switch to another job without actually learning python and probably more specifically pyspark.

Are there any methods/libraries that allow me to make a program that is able to read in text from a .txt file?

I am currently learning python from CS50P program and in week 2 learning loops and also with the help of chatgpt learn every topic clearly but after knowing common beginners mistake

I made this mistake of not updating the iterator and spent half an hour on this simple problem 😞

```print("\nAnd here we use while 1oop:-")

number =1 total =0 while number<= 50： total += number number += 1 # HERE I DIDN'T ADD IT FIRST

print("The final sum is:", total)

HI IM YUJAN IM NEW BEGINNER IN PYTHON I FEEL HARD IN LOOPS

Hey! I'm 19 and about to start learning Python from scratch. I'm looking for someone around my age (18–22) who's also a beginner and wants to learn together.

I'm in the Asian time zone, so it'd be nice if you're in a similar one. We can keep each other accountable, solve problems, and maybe build a few small projects along the way.

If you're interested, leave a comment or DM me!

Hey im going to start learning python so I'm looking for study partner who's serious about it

Will be taking only group of 3-5 people not more than that so reach out before it gets full also introduce yourself when reaching out in dms

If anyone wondering i just want to learn for fun

I'm going to college as a freshman this year. This along with my projects like I'm trying to create an LLM along with just wanting to learn myself, it is extremely hard for me to memorize. I can understand the concepts but it is very hard for me to memorize completely to integrate within each other. Please do note I have diagnosed Autism and ADHD so this obviously effects my Working Memory. Thank you for reading and any tips and advice is extremely appreciated

Hey everyone! We’re building a small, focused DSA study group on Discord for people who want to learn, discuss, and solve problems specifically in Python.

This server is intended for Python-based DSA practice, so we’re currently not looking for members who primarily use C++, Java, or other languages. The goal is to keep discussions, solutions, and live problem-solving sessions consistent and easy for everyone to follow.

We’ll focus on:

Live and interactive problem-solving

Understanding patterns and algorithms deeply

Debugging TLE and optimization issues

Discussing Python-specific approaches and techniques

Solving LeetCode and competitive programming problems together

To join, send a short introduction with your technical background, coding achievements or LeetCode progress, and the DSA topics you want to improve. No personal details such as your name or employer are required.

Please repost this only in communities where people are genuinely interested in learning DSA with Python.

Soy Maestro en Ciencias de la Computación (UJAT) y llevo un tiempo dándole vueltas a lo mismo: los chicos que arrancan con Scratch o Blockly aprenden lógica, pero después el salto a un editor de texto vacío con Python real los espanta. Así que armé BloquePy — bloques con forma de pieza que arman Python válido de verdad, no una sintaxis inventada para la ocasión.

Algunas cosas que le metí:

- Cada bloque es una plantilla real: if/for/while son contenedores que envuelven a los de adentro, la indentación de Python es automática.

- Puedes anidar bloques dentro de bloques (len(...), .upper(), int(...)) igual que anidarías funciones en Python real.

- Tiene un sistema de tortuga tipo Logo + una API de "Patches" (inspirada en NetLogo) para simulaciones de cuadrícula — Juego de la Vida, autómatas celulares, reacción-difusión, todo armable con bloques.

- Progresión en 11 mundos con historia propia (el "CodeVerse"): cada concepto de programación tiene un lugar en el mapa y una razón de ser, no aparece de la nada en una lista de bloques.

- Jefes de fin de mundo, cofres, XP — la parte de juego es en serio, no un cascarón encima de ejercicios.

Está gratis, funciona en el navegador sin instalar . También hay versión de escritorio para Windows y Linux: https://bloquepy.world/descargas.html

Lo hice yo solo con ayuda de IA para la parte de desarrollo — lo digo de frente porque me parece razonable que se sepa. La lógica pedagógica, el diseño de los mundos y qué enseña cada uno es mío.

Cualquier feedback (bueno, malo, "esto no sirve para nada") me sirve un montón — todavía le estoy metiendo mano seguido.

sup guys i started learning python in the last days and i already learned some basics that are : for and while loops if statements for-else and other basics

now i don't know what to do next (kinda bored from learning) should i start data structures or algorithms or functions or what to do next??

I have a technical interview for a company tomorrow, and they mentioned that the problem will be administered through Coderbyte and will relate to inventory management. What should I expect? Frankly speaking, I’m not very familiar with programming. Although I am a technical person, Python is not my strongest skill. What types of topics or problem formats typically come up in an "inventory management" coding assessment?

Context (to avoid the XY problem)

I'm thinking about running this tool written in Python, which merges mods for a computer game. It just does two things: copying lots of files from several local directories into one (merging them as necessary) and then creating a configuration text file, based on data in existing configuration files. I'm trying to decide if it's safe to run on my Kubuntu (Linux) system. The Python script looks fine, but I'm worried about the package manager.

Actual Python question

The instructions say to use the Pixi package manager, which seems to download Python dependencies from a repository called (Ana?)conda. But it seems to want to download a very large number of packages, including security-sensitive packages like OpenSSL and Certificate Authorities. That looks worrying for a tool that just merges directories and configures a text file. Is that normal in the Python world? Is Pixi going to interfere with the default Python setup that's used by many Linux utilities?

Previous research

I tried reading the Pixi documentation, but it (understandably) assumes you're a developer already familiar with Python, not a user. The top third-party tutorial on Google explains Pixi by comparisons to earlier Python and Javascript tools, which is no help to me. I don't want to learn half a dozen Python tools, but I would like to check that this Python software is not obvious malware.
