Hi,
On Windows 10, I uninstalled all previous versions of Python and
installed v3.9.6.
When I use the start menu option Python 3.9 (64-bit), I get the prompt
"Python 3.9.6" as expected. The same happens when I type "py" at the
DOS prompt.
But when I type "python" at the DOS prompt, I get "Python 3.8.10". I
don't understand this, as I uninstalled old versions, and I do not see a
DOS environment variable called "python" anywhere.
The real problem comes when I install a package, e.g. germalemma. Python
3.8.10 can use it, but Python 3.9.6 can't find it.
If 'py' starts 3.9, then
py -m pip install xyz
will install xyz for 3.9. (In not, py -3.9 -m pip ... will)
The command 'python' takes one to the MS store unless one has already
gotten the store python.
