 You may have to modify it depending on how you choose to report errors from your parser.
 If the scanner encounters an error it will throw an object of type :class`ScannerError`.

+Testing your solution
+---------------------
+A test script is available called test.py with an auxilary file called test.txt.
+You may test your solution by using the following command::
+  python3 test.py test.txt
+The output of running this test program should be something like this::
