This is pretty primitive implementation (do you really want to call
python from $PS1? ;-)

The git package contains the /etc/bash_completion.d/git file where
is defined function __git_ps1() which provides more usable strings
(it's able to detect if you are rebasing, bisecting, merging, ...) and
allows to use formatting for the string:

  $ echo $(__git_ps1 "git PS1 is: %s")
  git PS1 is: master


For example I use 

  PS1='\h:\w\[\033[0;32m\]\$\[\033[0m\] '
  PROMPT_COMMAND='printf "%*s\r" "$(($COLUMNS + 11))" "^[[33m$(__git_ps1 ":%s")^[(B^[[m"'

so I have "hostname:dirname$" on left side and ":branch" on right (the
branch name is yellow and '$' at the end of dirname is green:-)
