Python: How to not print comma in last element in a for loop?
list, python, string
Solution
print(', '.join(actorsByMovies()))
Problem
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?
