              Add your with code to your program, and let’s confirm that it continues to function as expected. Delete the two
              data files you created with the previous version of your program and then load your newest code into IDLE and give
              it a spin.

         No errors in the IDLE
         shell appears to indicate
         that the program ran
         successfully.



              If you check your folder, your two data files should’ve reappeared. Let’s take a closer look at the data file’s contents
              by opening them in your favorite text editor (or use IDLE).




                                                                               Here’s what the
                                                                               man said.















                         Here’s what the
                         other man said.








          You’ve saved the lists in two files containing what the Man said and what the Other
           man said. Your code is smart enough to handle any exceptions that Python or
           your operating system might throw at it.


           Well done. This is really coming along.

                                                                                      you are here 4    123
