Design a Do-While loop that asks the user to enter two numbers.
The numbers should be added and the sum displayed.
The loop should ask the user if he or she wishes to perform the operation again.
If so, the loop should repeat, otherwise it should terminate.

all in python code
thanks

Here is an example; a few notes:

- this is python 3.0; if you need an earlier version, let me know
- the loop continues as long as "Y" or "y" is entered for continue; anything else exits the loop
- this is a "while" loop - "do" isn't part of python, but the "while" loop, as constructed, performs all the functionality that "do" would entail; specifically, having the condition set to true (cont='y') before the loop starts creates an initial "do" condition so that the loop will execute at least once

--- python code:

n1 = 0
n2 = 0
cont = 'y'
while (cont == 'y' or cont == 'Y'):
n1 = int(input("Please enter first number: "))
n2 = int(input("Please enter second number: "))
print (n1, "+", n2, "=", n1+n2)
cont = input("Repeat (y/n)? ")
