stutter

Language/Type: Python list collections

Write a function named stutter that accepts a list of integers as a parameter and replaces every element with two copies of itself. For example, if a list named nums stores [1, 2, 3], the call of stutter(nums) should change it to store [1, 1, 2, 2, 3, 3].

Constraints: Do not use any auxiliary collections as storage.

Function: Write a Python function as described, not a complete program.
