Jason already showed you the answer, but significantly he also 
showed you how to find out for yourself. Use the >>> prompt. 
Its what its there for.

For some reason people use the >>> prompt wehen starting out 
in Python then seem to forget it exists. But the ability to try out 
little bits of code interactively as you develop code is one of 
Pythons most powerful features. One that it shares with Lisp 
Ruby and Smalltalk but surprisingly few other languages...

For those kinds of quiestions its usually much faster to just 
try it than it is to post a question to the list!
