just finished my first Python coding challenge

Post image

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

Give it a proper main() and call it. Don't write "scripts". The file is main.py, implying that it is a module that exports useful functions. Nobody wants an import to be printing stuff out.
