### 4. List Operations

#### List Operations:

The **+** operator concatenates lists:

>>> a = [1, 2, 3]

>>> b = [4, 5, 6]

>>> c = a + b

>>> c

[1, 2, 3, 4, 5, 6]

The ***** operator repeats a list a given number of times:

>>> [0] * 4

[0, 0, 0, 0]

>>> [1, 2, 3] * 3

[1, 2, 3, 1, 2, 3, 1, 2, 3]

The first example repeats `[0]`

four times. The second example repeats the list `[1, 2, 3] `

three times.
