No need to check the length of the list: """ >>> foo = [0, 1, 2, [3, 4, 5, 6, 7, [8, 9, 10]]] >>> isInNested(0, foo) True >>> isInNested(11, foo) False >>> isInNested(3, foo) True >>> isInNested(8, foo) True """ def isInNested(k, l): try: if k in l: return True for i in l: if isInNested(k, i): return True except TypeError: #l is not iterable pass return False if __name__ == "__main__": import doctest doctest.testmod() -- http://mail.python.org/mailman/listinfo/python-list
