This is what I would do ...
1.    Download Python from python.org not Microsoft
2.    Install as an expert or custom install to C:\Python310 rather than
C:\Program files
3.    Ignore this point - I was going to mention VirtualEnv which comes
later for software development and thereafter you don't need to put
Python on the Windows path. As I said, ignore this point.
4.    Add C:\Python310\Scripts to the path (system or user)
5.    Add C:\Python310 to the path after C:\Python310\Scripts
6.    Open a cmd prompt and enter python to prove it starts then quit.
Exit the cmd window
7.    Create a directory in the root of your user profile
(C:\Users\Jonathan ??) called pythontest
8.    Save 'print("hello world")' in a text file called hello.py in the
above directory
9.    Open a cmd prompt and type > python
C:\Users\Jonathan\pythontest\hello.py
Should work.
If you want to execute a python script without first opening a cmd
prompt, you need a bat file or shortcut which contains the command line
you want executed. Give that a double-click and it should also work.
If Python is on the path you don't need to specify where it is.
You do need to tell Python what you want it to execute.
It is possible that you can associate .py files with Python but that
would be a step too far for me.
Good luck

Signed email is an absolute defence against phishing. This email has
been signed with my private key. If you import my public key you can
automatically decrypt my signature and be sure it came from me. Just
ask and I'll send it to you. Your email software can handle signing.

I've never had to do that... But I have file associations set up so
that .py is considered to be an executable file.

Just double-clicking on the file will run it. The problem is that it
will open a command shell, run, and then close the command shell UNLESS one
explicitly codes some sort of "hold" at the end of the program

jnk = input("Press return to exit")

.pyw extension does not open the command shell -- but is meant for
programs that use one of the various GUI frameworks, which is probably more
than the new-comer is ready to attack.
