26. Using the higher order function reduce(), write a function max_in_list() that takes a list of numbers and returns the largest one. Then ask yourself: why define and call a new function, when I can just as well call the reduce() function directly?
from functools import reduce def max_in_list(num_list): def max_of_two(a, b): return a if a >= b else b biggest = float("-inf") return reduce(max_of_two, num_list, biggest) print(max_in_list([100,-2,3,4,5]))
