*args is needed when we want to pass an unknown number of unnamed arguments. If we put * before the name of the variable, this name will take not one argument, but several. Arguments are passed as a tuple and are available inside the function under the same name as the parameter name, only without *. Let's look at the example.


              
123456

            
def grocery_cart(*prices_of_all_fruits):
    total_price = 0
    for i in prices_of_all_fruits:
        total_price = total_price + i
    print(total_price)
grocery_cart(10, 7, 12, 13)

Task

You have to implement a function, named multiply_elements, that will take in an unknown number of arguments and multiply all of them together. Run created a function for this set of numbers:

  • (3, 6, 1, 2)
