collections.Counter()
A counter is a container that stores elements as dictionary keys, and their counts are stored as dictionary values.
>>> from collections import Counter
>>>
>>> myList = [1,1,2,3,4,5,3,2,3,4,2,1,2,3]
>>> print Counter(myList)
Counter({2: 4, 3: 4, 1: 3, 4: 2, 5: 1})
>>>
enumerate()
adds a counter to an iterable and returns it in a form of enumerate object. This enumerate object can then be used directly in for loops
