Functions as Objects

Question

def multiply(x, y):
return x * y

a = 4
b = 7
operation = multiply
print(operation(a, b))
can anyone explain how it code works?

Answer 1

multiply is a function that returns the multiplication of it's two arguments.
operation is assigned to multiply and does the same thing now as multiply so it returns 7*4=28

Answer 2

functions are objects, thus, you can assign them to a variable. So calling operation is EXACTLY the same as multiply, with the same arguments.

Answer 3

if I write operation = multiply then operation behave like multiply?
