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> a = MyTest()
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.
PS: Did I mention that zsh is the One True Shell? ;-)
