Make sure you add python to your system path

And try using python not python3

And try to run your code in native command line of windows

commands with python3 works for macOS/Linux. Use python for windows OS.

I ran into the same problem while creating a virtual environment for my project. Following instructions are quoted from https://code.visualstudio.com/docs/python/tutorial-django

macOS/Linux

sudo apt-get install python3-venv # If needed

python3 -m venv env

Windows

python -m venv env

Assuming you installed the Python launcher when you installed Python, even without python3 in your PATH, you should be able to launch Python with py -2 (to use the most recent installed Python 2 version) or py -3 (to use the most recent installed Python 3 version), thanks to PEP 397: Python launcher for Windows.
