Python Python Basics (2015) Logic in Python Product

What is the answer? I don't know if I'm doing the multiplication correctly because this language is chaos.

Should I be putting the result of it into a variable? Is there a math function I didn't use properly? I don't remember from earlier videos and I don't want to have to search for it to figure out how simple math works. I'm operating under the assumption python knows the difference between values... because that's how this language is sold so... what did i do wrong here?

product.py 
def product(num1, num2):
    num1 * num2 
    return
product(2,4)

def product(num1, num2):
    return num1 * num2 

product(2,4)

This is correct format

In function You do not store anywhere the product from num1 * num2 operation. This can be done by either assigning this to a new variable

prod = num1 * num2

or returning instantly

return num1 * num2

return in the last statement of your function will return None. After return you must give what you want to return

def prod(num1, num2):
    prod = num1 * num2
    return  # this will return None and thus None printed on Your console

print(prod(2, 3))
