boolean result of loop

[Skaperen]

a classic loop structure tests for one of a sequence of possible conditions.  in python the loop iterates over an iterator or equivalent (a sequence).  a variable starts at an initial state and is set by the condition.  it is then tested after the loop.

here is an example:

unsafe = False
for part in filename.split('/'):
    if part == '..':
        unsafe = True
if unsafe:
    raise UnsafeFileError(filename)

what i am looking for is if python has any simpler-code method for doing this kind of test.  since this is a example it needs to be not specific to this example.  any clues?
