What does and do

[Yoriz]

because

print(3 and 4)

returns an int

Output:
4

This explains it

Boolean Operations — and, or, not
These are the Boolean operations, ordered by ascending priority:

Output:
Operation      Result                                Notes
x or y         if x is false, then y, else x         (1)

x and y        if x is false, then x, else y         (2)

not x          if x is false, then True, else False  (3)

Notes:

1. This is a short-circuit operator, so it only evaluates the second argument if the first one is false.
   
2. This is a short-circuit operator, so it only evaluates the second argument if the first one is true.
   
3. not has a lower priority than non-Boolean operators, so not a == b is interpreted as not (a == b), and a == not b is a syntax error.
