You should probably post your babel configuration from .emacs. This
works for me (mostly). I'm using python 3.3 and so the print function
has changed to requiring parentheses. I can switch to a buffer called
*Python*, however, and =print("hi")= works fine.

If I change to =print(foo(100))=, I get 101 in the #+RESULTS block.

It's probably got something to do with your setup; taking a look at
your config should help others help you out.
