Essential Nested-Loop Convention in Python

AFAIK, this is the pythonic way to ripple breaks up through multiple loops in python.  It works in the scenario where we're trying to prove something, not to negate something, I think.

my_data = {'a': (1, 2, 3), 'b': (4, 5, 6), 'c': (7, 8, 9)}
for key, vals in my_data.items():
    for val in vals:
        if some_condition(val):
            break
    else:
        continue
    break
print "found", val, "at", key, "!"
