User's input after the program output

Question

I cannot do the user's input in the Sololearn sandbox. The idea is: the program's output is two numbers (a+b and abs(a-b)). And user should input these two numbers (a and b).
My ideas to do this are in the commented block.
Please give any suggestions. Thank you.

Answer 1

Granger, initially I did not mean to do 10 times loop, only once.
Later I added this loop just for the teachers to generate numerous variants of the task for schoolchildren.

Answer 2

Also the curious feature of the sandbox: even in the commented box it finds the input().
So I had to add # before input() to hide it completely.

Answer 3

codemonkey and Granger, thanks a lot.
Yes, I supposed the code will be functioning in any IDE.
So the principal problem is in the sandbox.
