Default and Keyword Arguments

Use default parameter values and keyword call syntax.

Introduction

Default parameter values and keyword call syntax make Python functions flexible and self-documenting.

def greet(name, greeting='Hello'): gives greeting a default. Callers can omit it.

def greet(name, greeting='Hello'):
    print(f'{greeting}, {name}!')
greet('Alice')
greet('Bob', 'Hi')
