With a python 3.X installed they need replace 'python' by 'py -3.X' in the
cmdline.
Examples, for a python 3.7 installation:
To invoke the interactive interpreter:
py -3.7
To run a script:
py -3.7 myscript.py
Another difference with unix-like OSes is that the python's Scripts directory
is not on the path, so pip (and other commands in Scripts) need a full
qualified path in the command, like
c:\python37\Scripts\pip install ...
or the alternative form
py -3.7 -m pip install ..
I don't know if it would be better to work from a venv:
Create venv
py -3.7 -m venv venv_path
Activate
venv_path\Scripts\activate
After that, in that console 'python' would be the python in the venv, and
venv_path\Scripts will be in the PATH, so commands like 'pip', 'pytest', etc
would work fine.
To deactivate the venv:
deactivate

python 3.8 has been tested more time; also 3.9 is not compatible with windows7,
which maybe some students have in their house.

I am teaching a Python class, where I use pygame to demonstrate OOP concepts.
I need to have my students get the proper environment to run Python with pygame.
I use a Mac, and I have Python 3.7.3, and pygame 1.9.6 installed. Everything
works fine for me. But I have students who either have Python already
installed and need to install pygame, or who need to install both Python and
pygame.
I am not a Windows user, and I typically don't use the command line for
anything other than installations. My understanding is that if you are on
Windows, and you want to use pygame, then during the installation of Python,
when the installation puts up dialog box about installing Python, you must
check the checkbox at the bottom that says:
Add Python 3.x to PATH
Question 1: If someone already has installed Python but did not check this box
on, is there some simple command line magic to do whatever this checkbox does?
If so, what do I need to tell my student to do?
Question 2: If someone does not have Python installed yet (or wants to install
a newer version), what is the most recent version of Python (Mac and Windows)
that I should ask them to install today? I understand that there is a big
effort to get the 2.0 version of Pygame out, but I want my students to use
version 1.9 for now. If they install the current version of Python: 3.9, will
they be able to use pip to install a working version of pygame 1.9? (Last time
I checked, this did not work correctly?
Thanks in advance,
Irv
