Python map()

You can apply a function f(x) on each element of a list A using the built in function map()

def f(x):
   return x**2 =1


A = [ 1, 2, 4, 0, 11, 10]

B = map(f, Z)


This gives an interesting idiom

C = map(int, raw_input().strip().split())

this takes space separated integers as input and stores in C.
