STEP 1

Create your own command.

A function is a set of actions with a name. The word def creates a function. After the name, you need brackets and colons.

def wave():
    print("Привет!")

✦ So far, the function has only been created and has not output anything.

STEP 2

To work, write the name of the function with brackets. It's a function call.

def wave():
    print("Привет!")
wave()

✦ Now it's going to be Hello!

IN-CLASS PRACTICE

Set an example. First the function is created, then called.

def hello():
    print("Здравствуй!")
hello()

HOMEWORK

The answer is hidden. Use similar examples from the lesson notes.
