Windows/Linux,macOS button has opposite syntax

[Steven Erredge]

Ex:
Click on Windows --> returns Linux/macOS shell syntax
...\> py -m django --version

Click on Linux/macOs --> returns Windows shell syntax
$ python -m django --version

py is the Python launcher which is Windows only. Does it not work on your system? I think it's installed by default.

The commands are correct.

On macOS/Linux (with bash) you'll get:

$ py -m django --version
-bash: py: command not found

Assuming you have Python on your PATH, or an active virtual environment both commands would work on Windows, but as Tim says py is the Python Launcher that's installed on Windows.

See: ​https://docs.python.org/3/using/windows.html#python-launcher-for-windows

Whilst you'll always have python available with an active venv, not having python on your PATH normally and using py to select the desired interpreter is (I think) recommended. (The install notes say "If selected, the install directory will be added to the system PATH" but don't say "Don't do this", as perhaps they might....)

If something is missing here, please reply and we can re-open if there's a mistake. Thanks!
