Don't know why, but recently, that shows me "master" in any folder,
even when there is no git repository, so I switched my PS1 to something
similar from above:

function bash_git_branch
{
  git branch 2> /dev/null | grep \* | awk '{print $2}'
}

export PS1='\[\033[01;32m\]\u@\h\[\033[01;34m\] \w\[\033[31m\]
$(bash_git_branch)\[\033[01;34m\]\$\[\033[00m\] '

So no need to call python, if awk is enought :)

Host and username are green, directory blue and branch red now.
