Python: How to not print comma in last element in a for loop?

My code iterates over a set and print actor's names:

for actor in actorsByMovies():
print actor+",",


The result looks like:

Brad Pitt, George Clooney,


But I want it to detect the last element so that it won't print the last comma. The result should be instead:

Brad Pitt, George Clooney


How can I do that?

Answer
print ', '.join(actorsByMovies())
