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.

Thanks to this course, you will learn what functions are, how to create them correctly in python. Start your course with introductory exercises, a structure for creating functions, and basic examples. in the end, you will learn what recursion is, how recursive functions are implemented in python, and you will also learn how to create more complex functions that, in your further practice, will greatly simplify and optimize your code.

Functions are one of the most important components of any programming language. Here we will learn how to create simple functions and see how use them to simplify the code

Parameters and arguments are a piece of information that is passed to a function. Here we will learn how to work with them.

In this section, we will learn what default parameters are and what they are used for. We will also learn how to create functions with them.

What if we don't know exactly how many arguments we will send? Here we will learn how to fix this problem.

Here we will learn how to create functions that are defined inside another function, and they are called inner or nested functions.

Recursion is a general mathematical and programming concept. Here we will learn how to implement recursive functions.
