Python Functions: From Zero to Hero
Unknown Number of Arguments
We used to work with functions when we knew how many parameters we were working with. What if we don't know exactly how many arguments we will send. Let's say we sometimes want to buy bananas, but not always. Let's look at the following example for this.
def grocery_cart(price_of_apples, price_of_carrots, price_of_oranges): total_price = price_of_apples +price_of_carrots + price_of_oranges print(total_price) grocery_cart(price_of_apples=10, price_of_carrots=7, price_of_oranges=12, price_of_bananas=13)
If we run the code above, we get a TypeError error, which is normal because this function expects 3 arguments, but gets 4 arguments instead, here the price of bananas is an unexpected argument.
However, functions in Python can handle an unknown number of arguments. This can be done in two different ways. We'll look at each of them separately in the following chapters.
