Default Argument Values

Snippet

You can assign a default value to a function parameter. If the caller doesn't provide a value, the default is used.

snippet.py
python
def greet(name="Guest"):
    print("Hello", name)
 
greet()
greet("Alice")

Breakdown

name="Guest"

Defines 'Guest' as the fallback value for the 'name' parameter.

greet()

Calls the function without an argument, so it uses the default value.
