Please you can correct and lecture me on some stuffs am a beginner

@Kim-Venom Here are a few changes that I would make, but I'm also newer to python. I added f strings to make it easier to read and write the code, I also was able to get rid of the need to be so redundant with adding the print statements. I did remove the os.clear because I could not see why it was needed, but you can add it back in if needed. Hope this helps some. If the f strings don't work for you then you are using python 2 and should uninstall it and start using python 3 as python 2 is at end of life and not under active dev anymore.

@Kim-Venom
No problem, glad I could help. If you ever have any questions let me know and I'll assist if I'm able.
You can also go to my repository and take a look at some small python projects for beginners. Here is a link to it.
You can also check out my YouTube Channel here I am about to start a python programming tutorial series.
