>>> def f (x): return x**2 ... >>> print f(8) 64 >>> >>> g = lambda x: x**2 >>> >>> print g(8) 64
The following is an excellent example I got from
>>> foo = [2, 18, 9, 22, 17, 24, 8, 12, 27] >>> >>> print filter(lambda x: x % 3 == 0, foo) [18, 9, 24, 12, 27] >>> >>> print map(lambda x: x * 2 + 10, foo) [14, 46, 28, 54, 44, 58, 26, 34, 64] >>> >>> print reduce(lambda x, y: x + y, foo) 139
