Help with "surrounding" a string

[cygnus_X1]

Below is one solution that works, just a number of simple
print statements in Python3

#!/usr/bin/env python
msg = input("Enter message:- ")
ch="*"
sp=" "
print(ch*(10+len(msg))) # print *
print(ch + (sp*(8+len(msg)))+ ch)
print("* " + msg + " *")
print(ch + (sp*(8+len(msg)))+ ch)
print(ch*(10+len(msg))) # print *

Below is the output:

Enter message:- Hello World
*********************
*                           *
*    Hello World     *
*                           *
*********************
You should be able to see how it works, it adds five "*" to beginning
and end of message, and adds a single "*" and four spaces to blank lines
