Python-mode provide a command for indenting that is bind to:

C-c # ==> comment
C-u C-c # ==> uncomment
The command is: `py-comment-region'

It is better to comment with that instead of the usual M-;
because it don't affect indentation after a block of commented code.

I don't know if python.el provide the same.
