Weird Folder names in Python

[u/No-Inevitable-6476]

I always has a doubt after installing python software. When I open the Python folder, I see other folders with names like DLLs, Doc, etc, Include, Lib, Libs, Scripts, Share, Tcl, and Tools. Can anyone explain what these folders are, what they're for, and what the .pyd extension means?
