What works for me is thinking about the while ... else construct
and comparing it to if ... else:
if x:
print "x is True"
else:
print "x is False"
while x:
print "x is True"
x -= 1 # or something
# A break here exits the loop with x True
else:
print "x is False"
then the step from while to for is obvious.
