The elements in a list can be accessed in the same way as the characters of a string by “slicing,” that is, with list[start:end]. In addition, Python provides countless functions and methods for processing lists.

>>> lst = [1, 2.3, 'abc', 'efg', 12]>>> lst[2]                # the third element    'abc'>>> lst[2:4]              # from the third to the fourth element    ['abc', 'efg']>>> lst[::-1]             # reverse order    [12, 'efg', 'abc', 2.3, 1]>>> lst[0] = 3            # changes the first list element>>> lst    [3, 2.3, 'abc', 'efg', 12]
