Language/Type: Python functional programming lists collections

Write a function named abs_sum that takes a list of integers as a parameter and returns the sum of the absolute values of each element in the list. For example, the absolute sum of [-1, 2, -4, 6, -9] is 22. If the list is empty, return 0.

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.
