Title
Body
I'm a big fan of Python's for...else syntax - it's surprising how often it's applicable, and how effectively it can simplify code. However, I've not figured out a nice way to use it in a generator, for example: def iterate(i): for value in i: yield value else: print 'i is empty' In the above example, I'd like the print statement to be executed only if i is empty. However, as else only respects break and return , it is always executed, regardless of the length of i . If it's impossible to use for...else in this way, what's the best approach to this so that the print statement is only executed when nothing is yielded?
