So I've been having trouble with Python and I want to know which installation I'm using (I have two user profiles on Windows, my old one and the one I made explicitly to code in, and they both have Python installed).

I tried looking it up, but it only led to this madness you see below:

    C:\Users\willi>!type python
    '!type' is not recognized as an internal or external command,

How do I view Python's location in command prompt?

I've installed python on 1 computer successfully after hours of reading stackoverflow suggestions, youtube videos, documentation etc. And after getting it on there and working I was so frustrated and lost that I had no idea what actions from which source actually worked.

Can someone walk me through this from step 1 why python never works after running the installer and needs all sorts of pointer adjustments in the PATH variable or X other variable like PYTHON PATH to places I can't even manage to keep track of? More specifically, today with a fresh install, what needs to be done to get python to actually install and be detectable by commands.

I'm obviously new, and mostly illiterate to the command prompt so that's part of my difficulty with going through stack overflow where answers 1 through 5 all do something completely different all in command prompt with various opaque arguments, hidden references, implied actions, implied paths etc.
