Question

a. Write a recursive function apply_all() that takes a function and a list as arguments and returns a list comprising the results of applying the function to each elements of the list. Example: >>> apply_all(sqrt, [4, 9, 16, 25]) # sqrt = square root function [2, 3, 4, 5] b. Use apply_all function to check which string in a list contains numbers only. apply_all(lambda:...., ["1234", "hellow","class23"])

Step 1

The function takes two arguments: a function (fun) and a list (lst). It returns a list comprising the results of applying the function to each element of the list. Here's the code for the apply_all function: ```python import math def apply_all(fun, lst): if Show more…
