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

See the docs:

x and y     if x is false, then x, else y

non-zero integers are treated as boolean true, so you get exactly the behavior described in the docs:

>>> a = 10
>>> b = 20
>>> a and b
20
>>> b and a
10
