Catching a Returned Function: Two Names, One Object

If `doubler` and `g` name the very same object, why would anyone return a function instead of just computing the answer outright?

Exercise 1 of 5

Catch what comes back

The video takes a chained one-liner apart and gives its first half a name. Do the same here: ask make_prod for the function that multiplies by 5, and catch what it hands back.

Assign that returned function to times5. Do not call it — times5 must end up holding the function object itself, not a number.

Given code — runs before yours

def make_prod(a):
    def g(b):
        return a * b
    return g

# Catch the function that the first half of the chain hands back.
times5 = ...  # your code here

# Catch the function that the first half of the chain hands back.
times5 = ...  # your code here
