Why is the answer zero for third line?

Question

print(1 == 1 and 2 == 2)

print(1 == 1 and 2 == 3)

print((1 != 1 and 2 == 2)+(2 < 1 and 3 > 6))

Answer 1

1 != 1 is false and its zero.
2 == 2 is true and its one.
It uses the and operator and since there is only one valid output, it outputs false,0.
2 < 1 is false and its zero.
3 > 6 is false and its zero.
It uses the and operator and since there are no valid outputs, it outputs false, 0.
Using the plus operator, 0 + 0 = 0.

Answer 2

In Python boolean is subclass of integer type. So when you use the '+' operator with boolean, it implicitly converts them to integer type.

Answer 3

That is because 'print False + False' gives you the value zero
