Using insert Method

The list.insert() method inserts an item at a given position. The first argument is the index of the element before which to insert. For example,

#!/usr/bin/python3

a = [1, 2, 3]
a.insert(0, 5)
print(a)
[5, 1, 2, 3]

Using Unpack List

The following example should cover whatever you are trying to do:

#!/usr/bin/python3

a = [1, 2, 3]
a = [5, *a]
print(a)
[5, 1, 2, 3]
