Extending a list

Two lists can be combined together using the extend() method. The day_of_week and sequence lists can be combined as follows:

    >>> day_of_week.extend(sequence)
    >>> day_of_week
    ['Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday',
    'Saturday', 1, 2, 3, 4, 5, 6]

Lists can also be combined as follows:

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

It is also possible to add a list as an element to another list:

    sequence.insert(6, [1, 2, 3])
    >>> sequence
    [1, 2, 3, 4, 5, 6, [1, 2, 3]]
