Looking for examples related to advanced python string, list and map operations

[A.M]

Hi,



Is there any online resource that gives examples about advanced python 
string, list and map operations?



Today I saw this and I found that I have to work more on mentioned topics:



numbers = [72, 101, 108, 108, 111, 44, 32, 119, 111, 114, 108, 100, 33]

print filter(lambda n: n % 2 == 0, numbers)



numbers = [72, 101, 108, 108, 111, 44, 32, 119, 111, 114, 108, 100, 33]

print reduce(lambda x, y: x+y, numbers)



Thank you,

Alan
