I agree. Wasted too much time on last few installs.
It got to the point I downloaded python-embedded, unzipped it and set
the path manually for my work (needed it as part of a compiler).
It ain't good enough. And I like python.

Or you can be smarter about how you calculate it.

While I think what you need is a database instead of the collection of

For whatever reason, Python installations on Windows lack versioned

adding multiple installations to PATH doesn't help unless "python.exe"
