Hi! Everyone, I am new to python and I want to learn it fully and clearly and want to make my fundamentals strong. Is there any specific video or website to learn basics and how many months does it usually takes to learn the python completely?

I am totally new to coding and working slowly through the course at futurecoder.io .

On the topic 'Introducing For Loops' we are asked to run the program:

name = 'World'
for character in name: print(character)

I figured character might be some kind of term that python recognises and knows what to do with, like print. Colour me surprised when replacing character with kitten runs, and has the same output. I thought maybe number in place of character might not work, since the characters are all letters, but it works too.

Why is it so? What concept do I need to grasp here?

I'm a second-year BCA student in Jaipur, learning Python alongside my coursework, and I built a small Telegram bot for myself that started out as one simple file. At first it just did one job, so a single file made sense. Then I kept adding features one at a time — a few more commands, some scheduled messages, a bit of stored data — and now it's a few hundred lines in one file and I'm honestly scared to touch it.

Every change feels risky because everything is tangled together. Functions call each other across unrelated features, I've got similar code copied in two places, and I'm never quite sure what will break if I move something. I've read about modules and packages, but most tutorials use tiny toy examples, and they don't show what the messy middle step looks like on a real, growing project.

So for people who've actually done this refactor: how did you decide where to split? By feature, by layer (commands vs data vs helpers), or something else? Did you move one piece at a time, or rewrite the structure in one go? And without a proper test suite, how did you check after each move that you hadn't broken something quietly?

I'm not looking for the textbook definition of a module — I want to know what your first real split looked like, and what mistake you'd avoid if you did it again.

I wrote a little Python script that reads in a text file that contains a list of fully qualified files, and checks to see if they exist. I originally wrote it using the argparse module. It was set up to take a filename and a switch, so the command looked like:

"Python dplcheck.py --plname "testing.lst” --showexist y"

This worked fine for a single file, but I wanted to run it for every one of hundreds of list files in a directory, so I wrote another script that generates a list of the .lst files in a directory and calls the first script for each one. But I could not get the second script to pass the arguments in the call to the first script. I tried subprocess.run and subprocess.call, with many different syntaxes and quotes, etc. I ended up removing the use of argparse and just using sys.argv[n] -- which I don't particularly like, since it has no defaults or error handling, etc.

Does anyone know how/if I can call a Python script from another Python script and pass the arguments when the called script uses argparse?

This is just for a personal/fun project--I want to learn how to use APIs because I want to play with sports stats (for the NHL/PWHL/international cricket plus a couple of less famous sports leagues like the SDHL). There's an overwhelming number of resources out there and I'm not sure where to start, so any tutorials/suggestions would be welcome. I know there are sport-specific API scrapers that simplify things but I'd like to learn how to do this more generally instead of having to learn a tool for every league.

I mostly program in Matlab but I do use Python sometimes, usually Jupyter notebooks. My coding knowledge is super patchy, I basically know a lot about my projects (data analysis for my research, with the data in specific formats), but very little about anything else.

(Yes, I could use AI, but for a project that's just for my own enjoyment I kinda just want to learn how to do it myself.)

I’m a brand new python user. Very experienced using R. I will be using python for LCA modeling via the brightway tool. For a python newbie, please drop any tips, tricks, learning guides. Ideally I need to get myself up to speed pretty quickly. Thank you in advance!

I'm trying to install marker-pdf and then hit with an error,

note: This error originates from a subprocess, and is likely not a problem with pip.

ERROR: Failed building wheel for pillow

Failed to build pillow

error: failed-wheel-build-for-install

I've tried to upgrade pip, reinstalling setuptools, wheel, pillow, and none works, the error remains. What should I do?

OS: Arch Linux
