What I do is set Python's sys.ps1 variable to something else. I have a
module called "interactive" that I import implicitly by shell alias:
py='python -i -c '\''import interactive'\'
Which, among other things, sets the prompt to "Python> "
433 $ py
Python> print "This has no leader that screws up email programs."
This has no leader that screws up email programs.
