The fastest way to access indexes of list within loop in Python 2.7 is to use the range method for small lists and enumerate method for medium and huge size lists. As the result, using range method is the fastest one up to list with 1000 items. For list w, If you have some given list, and want to iterate over its items and indices, you can use enumerate() : for index, item in enumerate(my_list): print ..., You can use enumerate : for k,i in enumerate(mylist): #do something with index k #do something with element i.
