I need this a lot: a one line way to do a n-ary and or 'or'.
Looks like there are itertools recipes for those, similar to what 
Michael just posted. Taken from here: 
http://docs.python.org/lib/itertools-recipes.html

def all(seq, pred=bool):
    "Returns True if pred(x) is True for every element in the iterable"
    for elem in ifilterfalse(pred, seq):
        return False
    return True
def any(seq, pred=bool):
    "Returns True if pred(x) is True for at least one element in the 
iterable"
    for elem in ifilter(pred, seq):
        return True
    return False
