Hello everyone,
I'm learning a python right now and just experimented a bit by writing a small program.
My problem is that the outcomming file size is pretty huge. It's ~150MB which I dont think is an appropriate size for a program of this kind. It's just a simple calculator for plotting circles.
Can someone give me a hint how to minimize the size? Maybe code or compiling changes will do it, but I'm not sure how to do it since I'm a beginner.
I know the code ist "complicated" and can be simplified for sure. But I wanted to keep it easy and didn't want to implement functions I've not learned yet.
Some advice for some cosmetic changes to reduce file and code size would be great!
greetings
