List operations

In this section, we are going to learn about basic list operations: concatenation and repetition.

The + operator concatenates lists:

>>> a = [30, 50, 60]
>>> b = ['Hello', 75, 66 ]
>>> c = a + b
>>> print c
[30,50,60,'Hello',75,66]

Similarly, the * operator repeats a list a given number of times:

>>> [0] * 4
[0, 0, 0, 0]
>>> ['Python'] * 3
['python', 'python', 'python']
