def greet(name, greeting="Hello"):

# output: john welcome

def describe_person(name, age=25, city="Unknown"):
    print(f"{name} is {age} years old and lives in {city}")

describe_person("Alice")
# Menggunakan kedua nilai bawaan

describe_person("Bob", 30)
# Menggunakan kota bawaan

describe_person("Charlie", 35, "New York")
# Tidak menggunakan nilai bawaan

# Benar:
def greet(name, greeting="Hello"):
    print(f"{greeting}, {name}!")

# Salah:
def greet(greeting="Hello", name):
    print(f"{greeting}, {name}!")
