It does allow both, and then a tab counts a 8 spaces. Mixing them is not
considered a good idea, though.

That looks terrible when you print it out, or when you look at it or write
it in email clients like Outlook, or have to place snippets in other
documentation. It's not obvious with Python code printed in books. And too
many editors will just mess it up. It would be incompatible with all the
Python already out there.
I don't use tabs at all. Just use 3 or 4 spaces like the rest of us...

It's part of the code itself, not only the documentation. It has semantics.

End then they stop hating it after 10 minutes or so. It's not a problem.

Forcing spaces or tabs may make things more consistent, but not more
pragmatic. And that's more important.
Luckily, there is no way that Python will implement this, not without any
obvious benefit and with ten years of Python code out there...
