(list of lists, object) -> tuple of two ints

Given a list of lists and an element, find the first

pair of indices at which that element is found and return

this as a tuple of two ints. The first int would be the

index of the sublist where the element occurs, and the

second int would be the index within this sublist where

it occurs.

>>> get_indices([[1, 3, 4], [5, 6, 7]], 1)

(0, 0)

>>> get_indices([[1, 3, 4], [5, 6, 7]], 7)

(1, 2)

Define a function called collapse() which takes a list as input. Each element of the list will either be an integer, or a list of integers. The function should modify the input list by replacing all of the elements which themselves are lists with the sum of their elements. For example: Test Result vals = [1, 2, 3, 4, 5] collapse(vals) print(vals) [1, 2, 3, 4, 5] vals = [1, [2, 3], 4, 5] collapse(vals) print(vals) [1, 5, 4, 5]...
