Project 4: ISBN Check With Loops

Modify your previous ISBN project so that the user may check as many ISBNs as they want, and they also can make repeated errors when entering the digits.

What you need to do

Modify your project 2 with the following enhancements:

In project 2, users could only make one error per digit. That is, they could enter a digit outside of the range 0-9 only once, and the program would ask them to fix it, but if they made a mistake on that same digit again, the program would simply continue. For this project, change your code so that they can make repeated errors and the program will continue asking them to fix it until they enter a digit in the correct range.
In project 2, users could only check a single ISBN each time the program was run. For this project, change your code so that after the user finishes entering an ISBN and they see the check digit, they are asked if they want to enter another ISBN. If they say yes, let them enter another one (and they can continue entering ISBNs until they decide to stop). If they say no, end the program.

Sample Interaction

Digit 1? 1
Digit 2? 5
Digit 3? 8
Digit 4? 2
Digit 5? 6
Digit 6? 1
Digit 7? 6
Digit 8? 8
Digit 9? 4
Last digit of ISBN should be 1.
Do you want to check another ISBN (type yes or no)? yes

Digit 1? 0
Digit 2? 6
Digit 3? 8
Digit 4? 8
Digit 5? -1
Bad digit, re-enter please.
Digit 5? 99
Bad digit, re-enter please.
Digit 5? 0
Digit 6? 6
Digit 7? 6
Digit 8? 7
Digit 9? -8
Bad digit, re-enter please.
Digit 9? 8
Last digit of ISBN should be X.
Do you want to check another ISBN (type yes or no)? no

Your code does not have to follow this exact script verbatim, but all the mentioned functionality should be there: asking for digits, printing the check digit, and not allowing digits out of range to be entered.

Hints

You will need to use one or more while loops in your code.

What to turn in

Through Moodle, turn in your code as a file called isbn_loops_yourLastName_yourFirstName.py.
