In this case, I'll use the following:

try:
    for item1 in range(10):
        for item2 in range(10):
                if item1 + item2 == 2:
                        print "Let's see"
                        raise StopIteration
except StopIteration:
    pass
print item1 + item2

And I tell you what. Actually I'm very lousy remembering things, and
if I want the loop to stop in a different number, I'll have to change
the code in TWO places. In mine, just one (and this in your codes get
worse with more for levels).

Another approach:

def bar():
    for item1 in range(10):
        for item2 in range(10):
                if item1 + item2 == 2:
                        print "Let's see"
                        return item1 + item2
foo = bar()
print foo
