Language/Type: Python functional programming lists collections

Write a function named double_list that takes a list as a parameter and returns a list of integers that contains double the elements in the initial list. For example, if the initial list is [2, -1, 4, 16], you should return [4, -2, 8, 32].

Use Python's functional programming constructs, such as list comprehensions, map, filter, reduce, to implement your function. Do not use any loops or recursion in your solution.

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