Python “and” operator with ints

Question

What is the explanation for this behavior in Python?

a = 10
b = 20
a and b # 20
b and a # 10

a and b evaluates to 20, while

Answer 1

In python everything that is not None, 0, False, "", [], (), {} is True

a and b is readed as True and True in this case the same for b and a

and yes in this case it takes the first value
