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?
