Functional Programming Tools: filter，,# 'filter(fu
# 'filter(function, sequence)' returns a sequence consisting of those items from # the sequence for which function(item) is true. If sequence is a string or tuple, # the result will be of the same type; otherwise, it is always a list. # For example, to compute some primes:def f(x): return x % 2 != 0 and x % 3 != 0print filter(f, range(2, 25))
