How can I append an item in a random location in a list in python?

append will add an item to the end of the list.

l = [1,2,3,4]
l.append(5)

outputs

[1, 2, 3, 4, 5]

now instead of adding 5 at the end of the list I would like to add it to a random location in the list. let's say 5 is being added to index 2. Number 3 will move one index forward.

[1,2,5,3,4]
