arguments, defaults, and the silent wrong-order bug

Write a function called greet that takes a name and an optional mood parameter. mood should default to "good". The function should return the string f"hi {name}, hope you're {mood}".

Then call greet twice and print both results:

• greet("alex") — uses the default
• greet("sam", "great") — overrides it

Expected output:

hi alex, hope you're good
hi sam, hope you're great
