Python Program to Create and call a Function

In the following example of Python program that creates and calls a function :

Program :

def greet(name):
    print("Hello, " + name + "!")

greet("Alice")
greet("Bob")
greet("Charlie")

Output :

Hello, Alice!
Hello, Bob!
Hello, Charlie!

In the above example, the `greet()` function takes one parameter, `name`, and prints a greeting message that includes the value of that parameter.

The function is called three times, with different values passed as the `name` argument.
