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
