Why and how does it work?

Question

Why and how does the empty class work?

class A(int):
pass
print(A(9) + A(9))
#output 18

The operator + is not overloaded. Moreover, there isn't anything that stores the int passed in.

Answer 1

Because A(int) means A is now a class and its parent class is int. Meaning that class A can do anything an int can do, add, subtract, or any other operation as well.

Answer 2

Slick int is a class? What about the other primitive types like string and float?

Answer 3

Yes, a class. Because remember, in python, EVERYTHING is an object. Strings and floats as well

Answer 4

Thank you!
