Does anyone know how it works??? need some help please

Question

def add(x, y):
return x + y

def do_twice(func, x, y):
return func(func(x, y), func(x, y))

a = 1
b = 2

print(do_twice(add, a, b))

Answer 1

Well, it feeds the do_twice() method with the add() method as both arguments and the function to perform. So you end up with add(add(1,2), add(1,2)), which performs (1+2)+(1+2)

Returns 6 obviously.
