Question

sum that takes a list of numbers lst, and uses functional operations to returns the sum of the absolute values from lst. import functools def get all sum(lst): ''' >>> get all sum([5, -1, 12, -10, 2, 8]) 38 ''' new lst

Answer 1

The student's question is about writing a Python function to calculate the sum of the absolute values from a list of numbers using functional programming techniques, including 'functools.reduce' and lambda functions. The provided example function, 'get_all_sum', correctly performs this operation.

Step-by-step explanation:

The student is asking about a Python function that computes the sum of absolute values of numbers in a list. The task involves using functional programming techniques in Python, specifically with the use of the functools module. To achieve this, one could utilize the reduce function from the functools module in conjunction with a lambda function that adds up the absolute values of the elements in the list.

Example Implementation:

import functools

def get_all_sum(lst):
return functools.reduce(lambda a, b: a + abs(b), lst, 0)

If we apply this function to the example list provided, such as [5, -1, 12, -10, 2, 8], the function get_all_sum would return the sum 38, which is the sum of the absolute values of the numbers.
