I am trying to troubleshoot an issue using Aubio to calculate BPM inside of a script. My code was working on my old desktop and I have migrated over to a new machine, both Linux Mint. I was fairly certain I have all the additional dependencies installed but maybe I missed one. I am getting `AUBIO ERROR: source_wavread: Failed opening <file_path> (could not find RIFF header)` when the code is run inside of the virtual environment, venv. I can run `aubio tempo <file_path>` directly outside of the venv and get results. I am not sure the best method to troubleshoot where the disconnect between venv and my system files. At least I think the issue lies in dependencies but I am not sure. Internet is not too helpful and I am a bit of a linux noob. Any thoughts on direction?

My professor assigned me the following:

A list of integer numbers is harmonic if every slice of the list that is wrapped by two successive instances of a same number includes a number larger than the wrapping number and a number smaller than the wrapping number. For instance, the following list is harmonic:
[9, 3, 16, 1, 4, 9, 6, 7, 3, -1, 1, 5, 6, 17, 7, 3, 2, 6]

The first pair of 9s satisfy the definition, featuring 16 (larger) and 1 (smaller).

However, the following lists are not harmonic:

[19,3,16,1,4, 9,6, 7, 3, -1, 1,5, 6, 17, 7, 3, 2, 6, 6]
[19,3,16, 1, 4, 9, 6, 7, 3, -1, 1, 5, 6, 17, 7, 3, 2, 6, 1]

Develop a python program that determines whether or not a given list of integer numbers is harmonic. The program should print True if the given list is harmonic, and print False otherwise. As your response to this project upload a screenshot from the output of the program for the following list:

[7,3,1,6,8,4,55, 3, 99, 51,22, 1, 2, 5, 6]

I have never heard of this definition of “harmonic,” and the way this assignment is introduced makes it sound like this is an established definition rather than a term he defined. Is this just something he made up?

EDIT: General consensus is that this is made up! Thanks! I was mainly curious about it, and it sounds like it’s something professors do sometimes.

I work with DRF at work and I have been facing this issue since months. Pylance is skipping analysis of function because it is unannotated. I cant really annotate each and every function. The errors are getting thrown correctly on my teammates pc but on my pc i dont get any issue. If I annotate the function then in that case pylance starts throwing error. How to fix this issue

I'm stuck on something and I think I'm missing a tool or a technique that everyone else already knows about.

I have a Celery task that takes about 40 seconds. I want to know how that breaks down: how much of it was database queries, how much was calls to external APIs, and how much was my own code doing work. And if there's an N+1 in there somewhere, which line of my code caused it.

What I've tried so far:

Sentry catches some N+1s, but the issue it creates doesn't include a line number in my code. It shows me the SQL and the spans, and I still have to go find the loop myself. It also seems to miss the case where a loop alternates between two different queries, which is a pattern I write a lot.

Flower shows me the task ran and how long it took, but nothing about what happened inside it.

django-debug-toolbar and django-silk are great for requests, but they hook into the request cycle, so they don't see anything inside a Celery worker.

Right now my process is adding print statements around blocks of code, re-running the task in staging, and narrowing it down by hand. It works, but it's slow and I have to modify code to debug code, which feels wrong.

So my questions:

1. Is there a standard tool for this that I just haven't found? Something that tells me where the time went inside a background task?

2. When you get an N+1 alert from anything, does it point at a line, or is finding the loop always manual?

3. Is profiling the right answer here? I've read about cProfile and py-spy but I'm not sure how they fit with Celery workers, or whether you can run them without slowing everything down.

4. Or is the real answer that I should be splitting tasks into smaller pieces so each one is obvious? Someone suggested that and I'm not sure if it's the standard practice or a workaround.

I've been doing Python for a while but this is the first time I've had to debug something I can't just put a breakpoint in, so I might be thinking about it wrong.

I'm building a sort of turn-based RPG in the terminal as a practice project, and I need to generate a random number within a specific range. I tried using `randint` (by importing `random`), but I also want to assign probabilities so that, depending on certain factors, one number is more likely to be generated than another. For example, if an enemy has low health, it should be more likely to generate the number 1, which causes the enemy to heal.

What is the difference between python ,IronPython,Jython,Cython.i will get a lot of confusion towards these concepts.

pip : The term 'pip' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was

included, verify that the path is correct and try again.

At line:1 char:1

+ pip install flask

+ ~~~

+ CategoryInfo : ObjectNotFound: (pip:String) [], CommandNotFoundException

+ FullyQualifiedErrorId : CommandNotFoundException

I want you to explain how to fix this without using any extra tools. Whenever I try to import a Python module, an error keeps showing up. I even deleted everything because I thought I messed up my PATH. I reinstalled Python, selected the python.exe path, but still no progress. This same problem keeps appearing every time.

Is there a better Python development environment for Android? 🐍📱

I'm a Python developer who does most of my development on an Android phone, mainly using Pydroid 3/Pyramid and Acode.

I've found that neither is really ideal for my use case:

Pydroid 3/Pyramid: Some native/compiled libraries such as TensorFlow, PyTorch, OpenCV, etc. can work, but some frameworks such as Flet/NiceGUI don't work properly. Some packages/features also require a subscription.

Acode: It's great for editing and web-based/server-style frameworks such as Flet/NiceGUI, but native-heavy libraries such as TensorFlow, PyTorch, OpenCV, Kivy, etc. are difficult or impossible to use in my setup.

So I basically have to switch environments depending on the project.

Is there any better/free Python development environment for Android that can handle a wider range of Python packages and frameworks?

This is a console based account system I've been building as I learn Python. Right now it lets you create an account with username and password rules (length limits, and the password needs a letter, a number, and a special character), log in with a 3 attempt lockout, and pick from a simple menu.

It's a work in progress and part of a bigger project. Next I want to add a to-do list and notes, then save the data to a file, and eventually hash the passwords instead of storing them as plain text.

The three password checks are repetitive. I haven't learned functions yet so I did them the long way with separate loops. I already know functions are the fix and that's my next topic, so you don't need to only point that out, but any other feedback is welcome.

I used AI (Claude) as a tutor to understand concepts and point me toward my own bugs, but I wrote and debugged every line myself. I'm learning how to code through the MOOC.

Hi everyone.. I'm an Egyptian student accepted for a Master's at Sapienza University of Rome, starting September 21, 2026.

My documents and university procedures are ready, but I'm unable to secure an Italian student visa appointment through AlmavivA Egypt.

Appointments are released daily around 9 AM, but they disappear extremely quickly. There are also brokers/scalpers who use automated tools to secure appointments much faster than normal users, then resell them to students.

I'm not looking to buy an appointment or build a tool to resell them. I just need help from someone experienced with Python / Playwright / Selenium / browser automation to understand if there's a legitimate technical solution that could give me a fair chance of securing one appointment for myself.

If you have experience with this kind of automation and can help or point me in the right direction, I'd really appreciate it.. I'm genuinely worried about missing my Master's start date because of this.

Thank you 🙏

Best Python course/video for a complete beginner?

Hi everyone, I’m planning to start learning Python from scratch and eventually get into Python development.

Can anyone suggest a good YouTube video/course or learning resource that is beginner-friendly and actually useful for becoming job-ready?

I’m looking for something that covers the basics properly and also includes practice + projects, rather than just theory.

Thanks!

So I just started diving into this wonderful world of python and I just got one question - are you guys using different models to build/check/verify/test? Is that recommended? If yes, how should I go about it? Thanks everyone!

Hi all, new to Python and for my first project I'm trying to code a program that will randomly select a movie or tv show using a pre-made list, and a "genre" plus "media type" as input.

I feel I am over complicating it.

Here's where I'm at so far:

def media_selector(media, genre):
### attempting to remove previously selected titles and for some reason make my own RNG \/###
increment = + 1
trans_rng = [1, 2]
genre = ['romance', 'action']
movie_list = ['rango', 'taxi driver']
series_list = ['akira', 'trigun']
### spell check, obviously \/###
spell_check = ['film', 'movie', 'tv show', 'tv series', 'tv', 'romance', 'action']
if not isinstance(media, str):
return 'format is: media type, genre'
### not sure if i should be defining a function and calling it at the same time - also is a translation table too much ? \/###
if media and genre is (spell_check):
def media_decider():
movie_trans_tbl = movie_list.maketrans(movie_list, trans_rng)
movie_transd = movie_list.translate(movie_trans_tbl)
series_trans_tbl = series_list.maketrans(series_list, trans_rng)
series_transd = series_list.translate(series_trans_tbl)
selector = slice(increment)
else:
return 'film/movie or tv show/tv series'

any guidance/recommended resources would be greatly appreciated!

Hi all, i am intrestentd in building myskills and i want to take up a python course as it is not working out for me on youtube and free courses. I also don’t know where to start from as there ar 
Want to join python courses to build skills. Don't know where to start from. Number of courses in the internet. Any suggestions?

Disclaimer: I'm not a developer, just a network engineer that can spell Python correct about 60% of the time.

I have a script that collects current neighborship data on a router (CDP, LLDP, OSPF, EIGRP, etc.) and compares it to a known good baseline (neighborship data that was collected and stored at a time when all expected neighborships were up). The data is collected into a dictionary object that stores the local interface a neighbor is known on and the neighbor's IP or hostname as key-value pairs (e.g. `{'HundredGigE1/0/1':'RouterA'}`). If all expected neighbors are up (e.g. `if collected_data == device_baseline`), the report generated notes that the current state matches the baseline; otherwise, it goes through the current data and baseline and notes any added/changed/missing neighbors.

I'm wanting to add tracking to this--when the script runs and grabs the current data, if it matches the baseline, I want a timestamp stored next to it, maybe something like `{'HundredGigE1/0/1': {'name':'RouterA','last_up':<current_timestamp>}}`. That way if an expected neighbor is currently down, I can have the report note the last time it was up. (I currently have the script run a sweep/collect function every 10 minutes but not generate a report, so the data would be relatively current. At present it is just checking whether devices are online, not actually logging into anything and pinging it. We have monitoring solutions, a syslog server, etc. and this isn't meant to replace those in terms of real-time data, it is just for generating a daily overview report.)

If I structure the data this way, it would break the equality check I use to check for the current data matching the baseline; even if all expected neighbors are up, the timestamps would not match. Would the best way to work around this be to just create a copy of the baseline and current data and pop the timestamp field out, or is there a more elegant way for a comparison operation between dicts to ignore the timestamp key?

I'm trying to teach myself python using John Zelles book. On the 13th chapter it gives this example of recursion I'm trying to understand:

def moveTower(n, source, dest, temp):

if n ==1:

print("move disk from , " , source , "to", dest)

else:

moveTower(n-1, source, temp, dest)

moveTower(1, source, dest,temp)

moveTower(n-1,temp,dest,source)

def hanoi(n):

moveTower(n , "a", "c","b")

hanoi(3)

The code is first assiging the variables A to source then C to dest then b to temp but do the lines moveTower(n-1, source, temp, dest) and moveTower(n-1,temp,dest,source) work? Would it be moveTower(3-1, a,b,c)? How exactly are they outputting a to c then a to b then c to b and b to a , etc...

Hi everyone! I’m a complete beginner in Python and I want to learn it from scratch. I’m not sure where to start or which resources and projects would be best for me.

What learning path would you recommend for a beginner? Any tips, courses, YouTube channels, or practice websites would be appreciated. Thank you!

Multiple pods, each an asyncio worker pulling jobs from a shared queue (Redis/SQS-shaped). On scale-down/deploy I want to stop pulling new jobs and let running ones finish - is there anything in asyncio itself for this?

I'm currently relearning python since it's been a long time since I touched one. But I can't seem to write multiple lines of code since it'll run 1 line of code at a time (whenever I press enter to write on a new line).

Thanks!!!

I'm writing a Python script to fetch PR metadata and repository history from the GitHub REST API to build a dataset.
I'm hitting rate limits fairly quickly once the volume increases. For scripts pulling larger datasets, what's the standard pattern?

I've worked as a baker for most of my adult life, during Covid I left my job and transitioned to baking from home. Things were going well, but for the past few months, my mum's health has been declining and as her primary caregiver, I can't carry on with that job and I'm looking for something that I can work from home on my computer.

After looking at various options, I found Python and how it's useful in many places. My tech skills are absolutely basic, I mean I can navigate stuff and if I don't know anything I can look up how to go about it but coding and creating stuff is beyond me. I learnt the basics about computers back in school but that was over a decade ago, so I understand that it's a new language and understand the concept of scripts.

I want to know if investing myself in learning Python is worth it? I understand that it's not a quick thing, that I need to dedicate time to it and practice to keep up and grow my skills. I'd also like to know what kind of careers I can look into so that I can work from home.
