In Python, you can specify default arguments by assigning them a value in the function definition.

use the input function to ask them their name like name = input(" enter name?: ") or

def greet(name, msg):

    # This function greets to  the person with the provided message

 print("Hello", name + ', ' + msg)  

greet("Andy", "Good morning!")

def greet(name, msg="Good morning!"):

   # This function greets to

     the person with the

     provided message.  

     If the message is not provided,

     it defaults to "Good

     morning!  

   print("Hello", name + ', ' + msg)

greet("Kate")

greet("Bruce", "How do you do?")
