this is what it did for me:

Output:
lt1a/forums/2 /home/forums 6> box try.py
+----<try.py>------------------------------------+
| x = input('Please enter an integer value: 2 ') |
| y = input('Please enter an integer value: 7 ') |
| num1 = int(x)                                  |
| num2 = int(y)                                  |
| print(num1, '+', num2, '=', num1 + num2)       |
+------------------------------------------------+
lt1a/forums/2 /home/forums 7> py try.py
Please enter an integer value: 2 2
Please enter an integer value: 7 7
2 + 7 = 9

simple explanation for others:

if you type just the Return key only, you get an empty string. input() does not get a number from the end of the output.

YOUR CODE needs to check for an empty string and substitute the default input, if that is you intention.
