Flexible functions

Call functions with default values and keyword arguments.

Provide a default

A default parameter is used when the caller omits that argument. Required parameters come before parameters with defaults.

def greet(name, greeting="Hello"):
    return f"{greeting}, {name}"

print(greet("Ada"))

Output

Hello, Ada

Keyword arguments make the meaning of a call explicit and can be supplied in a different order.

def price(amount, tax=0.2):
    return round(amount * (1 + tax), 2)

print(price(tax=0.1, amount=50))

Output

55.0
