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.
