I usually either run a python session in an xterm (bad for multiline), or
do python -c '...' multiline.  In zsh  ;-)

Really, try the zsh... I with readline were as good as zsh's ZLE.
Kick-Ass (really) multiline editing.  And a history that correctly
deals with it.

You can also edit here-documents...

    ~ % python <<EOF
    heredoc> class MyTest:
    heredoc>     def __init__(self):
    heredoc>          print "I'm ready"
    heredoc> 
    heredoc> a = MyTest()
    heredoc> EOF
    I'm ready
    ~ %

Which is much better than -c, because you don't have to worry about
quoting (the snippet above, with the ' inside a ", gets complicated
inside *another* pair of ')

Go back in history, and edit the little snippet... no problem.

Bye, J

PS: Did I mention that zsh is the One True Shell?  ;-)
