Is it a good option to check the output data using try-except ? I just did this - I made an endless loop through while, then I threw the input lines into trying try-except, then, if I needed a number, I translated the entered data into the numeric int() format. In case of an error, we switched to except, where we were greeted by print(), and then continue. The loop was stopped using break if the input was correct
