Let's get to know each other. I wrote a function that will output my name to you, and you will write a function that will output your name.

def say_my_name():
    print('My name is Heisenberg')

say_my_name()

So, the `say_my_name` function simply prints the phrase `'My name is Heisenberg'` to the screen, and we can call this function to see this output.

Now we will consider what a function in Python and some basic techniques used to create functions is: what are the arguments of the function, what is the return value of the function, what is the body of the function, and how to use the function in the code.

Python is a fairly flexible language in terms of creating functions. This is especially true in setting function arguments - there are several different types of function arguments, and you can choose any of them depending on the problem you are solving. Let's now take a closer look at them.

The return value of a function is the direct result of the execution of the function, which we can use in the program. There are several types of function return values - now we will consider the most commonly used.

Now it's time to consider additional topics to help make your functions more flexible and solve more complicated tasks. You will understand recursion, lambda functions, and some basics principles of writing effective and maintainable functions.
