Functions with Default Parameters

Snippet

You can provide a default value for a function parameter. If the caller doesn't provide an argument, the default is used.

snippet.py
python
def greet(name="Guest"):
    print("Hello, " + name)
 
greet()          # Uses default
greet("Alice")   # Uses provided value

Breakdown

name="Guest"

Defines 'Guest' as the fallback value if no name is provided.

greet()

Calls the function without arguments, triggering the default behavior.
