I am starting a python project that needs Python 3.6 and on my computer I have only installed Python 3.9(which is added to PATH).
When I am installing Python 3.6, should I add it to PATH because Python 3.9 is already added to PATH? If yes, what can I do to specify what Python version I want to use?
When installing a package, how can I specify that I want to use Python 3.6 to install this package?
How can I change my command prompt to use Python 3.6 instead of Python 3.9?
