Разбор Python-задачи

Если вы ответил 2 — это ловушка

def func(a, b):
    res = a + b

res = func(1, 1)
print(res)

На первый взгляд кажется, что res = 2. Но нет.

➡️

Что происходит

1. Функция func(a, b) складывает a + b и сохраняет в переменную res внутри функции.

2. Но! Функция ничего не возвращает. В Python по умолчанию любая функция без return возвращает None.

3. Следовательно, res = func(1, 1) присваивает None.

4. На экран выводится None.
