[Tutor] c++::return

[elis aeris]

I actually said "ending" to avoid problems with different terminology
between different languages - but i guess a return is still a return in
python.

i did this search

http://www.google.ca/search?hl=en&q=python+tutorial+return&btnG=Google+Search&meta=

and it didn't return any particularly obvious answer.

The funny thing is, i wrote that program last june and managed to not
know/use a single return :)
