For this lab your goal will be to add a assert statements to the PyNote program from Lab $3.$ The program has been updated with some new features. As the PyNote program continues to grow, we want to introduce some simple tests so that we know when we break a critical feature. A python code named lab$5.$py has been provided for you here Download here. The lab$5$ code is already functional.

You are free to implement your code however you want, but it must include the following requirements:

An assert statements to test that the is$\_$int function returns expected results given an argument of any type.

An assert statement that raises an AssertionError when a FileNotFoundError is not raised when the remove$\_$note function is called, but the "pynote.txt$"$ file does not exist.

Once you have completed both $1$ and $2,$ modify the remove$\_$note function so that it passes $2.$

Some considerations

You will need to consider where to place each of these assert statements so that they run when the program is run.

To test requirement $2,$ you will need to delete the PyNote.txt file while the program is running.
