Python standard indention is 4 spaces. If you want to go to the source on
this here is what Guido van Rossum has to say about it here:
http://www.python.org/doc/essays/styleguide.html

Indentation
Use the default of Emacs Python-mode: 4 spaces for one indentation level. For
really old code that you don't want to mess up, you can continue to use
8-space tabs. Emacs Python-mode auto-detects the prevailing indentation level
used in a file and sets its indentation parameters accordingly.
Tabs or Spaces?
Never mix tabs and spaces. The most popular way of indenting Python is
with spaces only. The second-most popular way is with tabs only. Code indented
with a mixture of tabs and spaces should be converted to using spaces
exclusively. (In Emacs, select the whole buffer and hit ESC-x untabify.) When
invoking the python command line interpreter with the -t option, it issues
warnings about code that illegally mixes tabs and spaces. When using -tt these
warnings become errors. These options are highly recommended!

For better or ill that is what the Python community has come to embrace.

Yes, but vim uses tabstop to determine how many spaces to put in. Hence
tabstop to 4, expandtabs on, shiftwidth to 4. Tabstops to know what to do
when we hit tab, expandtabs on so we don't send it out to other people,
shiftwidth to know what to do when we want to reindent.
