*args
*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.

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)

It's time to practice.
