One of the tests of your code should be for an input list representing a possible ISBN number

partly based on the example given above and partly derived from your $\frac{?}{PI}$ number. So$,$ the first

six digits in your ISBN list should be the first six digits from your PI number and the remaining

digits will be $1,1,8,3,2,1,3.$ So$,$ for example, for the PI number B$9081720,$ your ISBN list

will be:

$9,0,8,1,7,2,1,1,8,3,2,1,3$

The first part of this question will only consider the following part of the decomposition.

$>$ Check ISBN number$>>$ Make a new list by leaving the items at the even indexes $($including $0)$ unchanged

and multiplying the items at the odd indexes by $3$

You may want to temporarily add a print statement to check the output.

a$.$

i$.$ Describe the input data and the output data for this first task.

ii$.$ Specify one further input list you might use in testing in addition to the list you have

created using your PI number. Make sure that you state the test input, the

expected output and a brief explanation of why you selected this test.

iii. Write an algorithm based on Pattern $2\mathrm{.}4.$

iv$.$ Implement your algorithm as Python code. Your code must match the steps of your

algorithm and you should use comments in the code to make it clear how the two

correspond. Marks will be lost if the program does not follow the algorithm. Copy

your Python code, as text, into your Solution document. Name your Python file

Q$2$a$\_$OUCU.py$,$ where 'OUCU' is your OU computer username, e$.$g$.$ abc$123.$ Then

include the code file in your TMA zip file.
