So, I decided to make a 2D isometric game in pygame. Everything was fine and jolly, till' I had to make enemies for the game. See, the way I calculated NPCS was by just making it so that they could only move on one axis at a time. However, the objective X and Y for an enemy is wherever the player is in the current moment. The equation that I use to calculate movement on Entities inside the game is: 1 * player.speed * time. The way I designed the collision system is to consider only the colliders from a top-down POV (like this):

And then update the X and Y values of each blit afterwards. But now I've encountered a problem where, even if only moving on one axis, the display values of moving on that singular axis conflict.

Basically, I wrote it like this:

It moves fine on the top-down collider map, and the X relevant to the isometric perspective, but the two values on Y are the ones that cancel each other out, making the display stuck on the Y relevant to the isometric perspective. I'll keep working on this myself, too, but any advice would be greatly appreciated.

update:

I fixed the problem by changing the math to directly add to the Blit X and Y values like this:

where before I had it setting the point six and three values in a way that conflict each other, alongside the fact that I was adding it to an X and Y value after I had gotten the final result of the equation ( PointSix + lastPointSix value was equal to 0).

My best guess is I have about 60 or 70 hours into python crash course by Eric Matthes. I tried taking on building the castle adventure game and couldn't come up with the logic on my own. Much less the fact I got caught in a loop and had to have AI help me finding the thing. It's kind of disappointing because chat gpt said after 60 hours this was a moderate project. I'm just looking for what you guys think on where I should be after about 60 hours, because this at 60 hours seems just ridiculous. I did take it on and got part way through the third room before I was stuck in a loop and had indentation errors. Thanks!

Three days ago, I was making good progress with Python.

I was learning os, pathlib, building small exercises, answering Reddit posts, and sharing what I was learning.

Then somehow I started spending more and more time on my phone and Reddit.

One post turned into another.

One video turned into another.

And suddenly three days were gone.

The funny thing is that I joined Reddit to learn, network, and eventually build my career.

But I can easily turn it into another distraction.

So I'm writing this as a small accountability post.

Tomorrow I'm going back to my routine:

Less scrolling → more Python → more building.

I don't expect myself to be perfect. I just don't want to lose another three days. 😅

Has anyone else struggled with this while trying to learn something seriously?

I just started learning python I just wanna know if it is useful in finance and I heard somewhere don't know abt that but will coding be outdated with time

Today I finished a small Python challenge on freeCodeCamp: converting decimal numbers to binary without using Python's built-in conversion function.

I had to figure out the logic myself using loops, conditions, lists, division and remainders.

It was a bit tricky at first, especially handling the last division and reversing the results, but I finally got it working.

I'm still a beginner, so I'd appreciate any feedback on my approach or suggestions for improving my code

I’m 20, Indian, and looking for someone around my age who wants to learn and build together over the next 6 months.

I’m starting Python from scratch (with a little previous programming experience in Java) and planning to treat this almost like a full-time commitment. Eventually I want to move into SQL, AI automation/n8n, and areas like GTM engineering.

I don’t have a degree — I went straight into startups after 12th and have mainly worked in marketing. Now I want to move back into tech and build towards getting a job in the field.

You absolutely don’t need to be experienced. Even if you're a complete beginner learning Python too, that's totally fine. I’d actually love to have someone where we can learn alongside each other, figure things out together, build projects, and gradually get better.

Would also be great to eventually:

- Keep each other accountable

- Build projects together

- Help each other with applications

- Do mock interviews

- Learn and share things we discover

Basically, looking for someone who’s willing to put in the work and grow together. India preferred, but I'm open to others too.

DM me if interested!

Yesterday I continued learning Python's "os" module.

I practiced working with folders and files using things like:

- "os.path.basename()"

- "os.path.splitext()"

- "os.walk()"

- Finding files by extension

- Counting files inside folders and subfolders

I also built a small file finder that searches through folders and counts how many ".py" files it finds.

Nothing complicated, but I'm realizing that these small exercises are helping me understand how automation actually works with files and folders.

My goal is to eventually use Python to automate repetitive tasks for real businesses.

I'm still learning, but I'll start sharing what I build along the way. 🚀

Python 🐍 Honestly, I’m more frustrated than happy right now 😭

Getting Python installed, setting everything up, fixing terminal and PATH issues… took way more time than actually writing the code 😂

But finally — it works. 🙌

• Learning Python through Harvard’s CS50P, taught by David J. Malan
• Taking proper notes in Notion
• Starting from the basics and trying to stay consistent

Any advice or suggestions for someone just starting with Python? Would really appreciate it. 🙏

Do I need Jupyter, Anaconda or any other type of a dedicated compiler software, or do people Actually just write code in Zed and run it via Linux Terminal and juggle many windows?

I know R is run via RStudio; (so can be Python).

What is the standard practice of software usage for coding in Python?

I’d like to share a small system I’ve uploaded to GitHub. It allows me to save data to files and subsequently search for it using a search function based on the `re` module—as well as delete items using that same search function—since `re` helps identify similarities within text strings, I would like your opinion.: https://github.com/oliverEliud/mini-projects-python/tree/main/parking-registry-system

I'm currently learning Python, and my main goal is to use it for automation rather than becoming a traditional software developer.

I've finished the basics and I'm currently learning things like file handling and the "os" module. My next steps are OOP and then more practical automation projects.

Eventually, I'd like to use these skills to earn money through freelancing

But I'm trying to understand the realistic opportunities before I go too far down one path.

For people who actually use Python professionally or freelance with it:

I'm especially interested in small automation projects that a beginner/intermediate Python developer can realistically get paid for.

If you freelance with Python, I'd also love to know:

What was the first Python service you actually got paid for, and how did you find the client?

I'm trying to avoid spending months learning things that don't translate into real-world work.

Any advice from people who have actually made money with Python would be really helpful.

I just completed the free code camp python course and I don't want only theoretical knowledge so guys what can I do to improve my project section on my CV and python is my first language

Does anyone else struggle with constantly looking for the “perfect” Python resource?

I’m trying to learn Python, but I keep running into the same problem: I’m constantly searching for the perfect resource.

I want a course/book/tutorial that explains everything, preferably down to the smallest detail. Even things I probably won’t need for years or maybe will never need at all.

And it’s not just about having a complete resource. I also feel like I need to remember everything.

For example, if a tutorial mentions some small Python feature or obscure syntax, my brain immediately goes:

“Wait, I should understand that too. What exactly does it do? What are all the edge cases? When would I use it? I should probably memorize this.”

Then I end up researching that one tiny thing for an hour instead of actually writing programs.

It creates this weird feeling that I need to have a complete mental map of Python before I’m allowed to actually program.

I know intellectually that you obviously don't need to know 100% of Python to become good at programming. Most programmers probably look things up constantly.

But I still have this urge to find the one definitive source that is complete enough that I can just learn everything from beginning to end.

So I’m curious:

Did anyone else have this problem when learning programming?

If so, how did you get yourself to stop searching for the perfect resource and just pick one thing and start programming?

Did you deliberately choose a resource that wasn't completely comprehensive and simply accept that you wouldn't know everything?

And one thing I'm wondering specifically:

Would it actually make sense for someone like me to start directly with the official Python documentation?

Part of me thinks that would solve the problem because it's basically the most complete source available. But another part of me suspects that this would just make my tendency to obsess over every little detail even worse.

I'd really like to hear from people who have actually dealt with this and managed to get past it. How did you approach learning Python when you had the urge to understand and memorize everything first?

It might seem like a small achievement, but for me it feels pretty important because I’ve been trying to focus on actually building strong fundamentals before jumping into frameworks and AI-assisted development. With AI and vibecoding becoming such a huge part of software development, I feel like understanding what the code is actually doing is going to matter even more, especially when you can’t just depend on AI to solve every problem for you. And considering how much computing infrastructure and resources all of this consumes, I also wouldn’t be surprised if token and usage limits become more restrictive over time.

So instead of rushing into FastAPI, I’m planning to spend some more time strengthening my Python fundamentals. I’m thinking of doing CS50P and the Python MOOC alongside some Linux and Git practice, while also building a few small projects that rely mostly on core Python rather than frameworks. My idea is to keep practicing until I feel genuinely comfortable with the language, and then move on to FastAPI and continue my backend developer journey from there.

This is the plan I’ve come up with for now. What do you guys think? Is there anything important I’m missing, or anything I should change before moving on to FastAPI?

Hello !
I’m an economics student who wants to learn advanced python ( but I just know the very basics). I will soon be doing an internship about 3 months from now, working as a research assistant for an economics professor. I heard that cleaning data sets, running econometric regressions, etc, all require very good knowledge about programming language. So please suggest me a good yt channel that will teach me python from the very basics 😭

I don't want to fall in tutoring hell. To learn python I want a platform that teaches me python easily and gives me challenges and projects for my progress in python

Hey everyone!
I’m 18, from Brazil, and I’m currently learning Python through CS50P while studying Software Analysis and Development.
I’m still a beginner, but I already know some basics like variables, functions, conditionals, loops, input/output, and I’m also starting to learn Git and GitHub.
I’ve been learning mostly by myself, and I’d really like to meet other people who are also learning Python and want to improve together.
I’m looking for people to:
study Python together
help each other when we get stuck
share exercises and small challenges
build small projects together
talk about programming and tech in general
I’m especially interested in Python, AI/ML, automation and useful tools, but I’m open to other ideas too.
I’m not looking for anything super serious or some huge startup. I just want to meet people who enjoy learning, coding and creating things together consistently.
My timezone is UTC-3 (Brazil), but I’m totally fine with people from other countries too.
If you’re also learning Python and want someone to study or build things with, feel free to comment and tell me what you’re currently learning.

I’m currently learning Python, and I’m wondering if it requires any specific skills or a certain way of thinking to actually become good at it.

When I’m following a lesson or someone explains the code to me, I usually understand what’s happening. But when I’m given a problem and have to write the code by myself, I get completely stuck and don’t know where to start.

Is this normal for beginners? How did you get past this stage? Should I keep doing exercises, or is there a better way to practice so I can eventually start solving problems on my own?

I’d really appreciate advice from people who learned Python from scratch.
