There's bash in there, and I think there's some Python; some plugins (git-svn) are in Perl. I also wasn't under the impression that there were 10 languages there.
I believe python is required only for building the docs (html/man) as they are written in asciidoc.
There are precompiled docs (git-manpages / git-htmlpages) in the kernel.org git dir[1], so most often that isn't needed.

edit: Looks like there are a few importers written in python as well, but those are entirely optional.
