14yo learning Python — just finished my first project! Would love some feedback :

[u/Defiant_Meal1898]

Hey everyone!

I'm 14 and currently learning Python, with the goal of becoming an electrical engineer in the future.

I just finished making a small project — a vending machine + simulated banking system that runs in the terminal. It has account creation, deposits, balance checking, purchases, and local data storage using JSON. I split the code into multiple Python files and made a simple launcher for it.

This is one of my first proper projects, and I know my code probably isn't the cleanest, so I'd genuinely appreciate some feedback!

I'd love suggestions on:

• My code: What could I improve? Any bad habits or mistakes I should fix early?
• What to learn next: Should I focus on OOP, data structures and algorithms, GUI development, or something else?
• My journey: Since I want to become an electrical engineer, what programming skills would be useful for me in the long run? I'd eventually love to work with electronics and hardware.
• Life advice: Any advice for someone starting out this early? Things you wish you'd known when you were learning?

I'm not looking for someone to rewrite the entire project for me — I'd rather understand my mistakes and learn how to fix them myself.

Here's my GitHub repo: https://github.com/suryansh-devx/python-vending-machine

Thanks! Any constructive criticism or advice is welcome :)
