STEP 1

The function may have a backup option

The value after = inside the brackets of the function is used if nothing is transmitted when calling.

def greet(name="друг"):
    print("Привет, " + name)
greet()

✦ «Привет, друг» will appear.

STEP 2

If you transfer the name in parentheses, you will not need a spare version.

def greet(name="друг"):
    print("Привет, " + name)
greet("Лев")

✦ Now «Привет, Лев» will appear.

IN-CLASS PRACTICE

Dial the function and call it without argument.

def wave(name="друг"):
    print("Привет, " + name)
wave()
