Does my explanation make sense?

Question

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

#if anything was added as print (5,10) the answer would be normal as 15

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

#what is func? it is a third argument. Isn't supoose to be add(x,y) instead of func?
a = 5
b = 10

print(do_twice(add, a, b))
#here add= the first function which return 15
then the do_twice function should do something?!
