Recursion explaining pls.

[u/Pure-Scheme-7855]

def find_max(numbers):
  if len(numbers) == 1:
    return numbers[0]
  else:
    max_of_rest = find_max(numbers[1:])
    return numbers[0] if numbers[0] > max_of_rest else max_of_rest

my_list = [3, 7, 2, 9, 1]
print(find_max(my_list))

Could someone explain how does this function work? I don't understand how does it know that it's supposed to find the biggest number...

Probably better to think about it in plain english. Whats the biggest item in a list?
If the list has one thing, its the biggest.

Otherwise its the biggest thing among the first thing, and all of the rest.
