How do I implement cmd's auto-tab-completion to python?

Sorry for messy code, I have written an "Alternative Command Prompt" with some fun tools in addition to some really simple commands. I have searched for days trying to find a way to implement cmd's tab completion to my code. Can someone please help?

I tried multiple things such as using pyreadline or readline but none of them seemed to be able to replicate the behavior in Windows's cmd. There are some other modules that kinda seemed to work, but it wasn't really functioning the way I wanted.
