Important

• Remember the University accepted you because you are an outstanding student.

• Based on your past educational achievements, I expect you to do well on this test.

---

Notices

• Answer the questions in any order that you want.

• I suggest you do things the easiest way possible. There are no intended trick questions. Each module has a straight-forward answer (e.g., my modules all together had less than fifty lines of code).

• All modules have the same worth, so do them in the order that you find them easiest. They are asked in the order, that I thought would be easiest.

• To make things go smoother, you are strongly encouraged to submit as you go along.

Test rules

• You must use my download files.

• Hand in both parts of the test.

• Before you leave the room check that you uploaded all of your solutions. Do not ask afterwards whether you can submit a forgotten solution.

• This pledged exam is closed notes. The only device you may access during the test is your laptop.

• Uploading after you leave the room means you are withdrawing from the class.

• Do not access class examples, web solutions, or your own past assignments during the test; that is, the only code you may access or view are ones that you develop for this test.

• The only windows to be open on your computer are PyCharm and a single browser with tabs reachable from the class website.

• PyCharm can be used for developing the modules to be submitted. It cannot be used for the short answer questions.

• With regard to your functions:

• Comments including header identifying comments are not necessary.

• You should follow other class style practices; e.g., whitespace, identifier naming, etc.

• Only do what is requested.

• None of the functions should get input or produce output.

• Functions should not modify their parameters in any way.

• Whether a function is testable (compiles) is important.

• Any form of cheating on a test can result in expulsion from the class and the incident being referred to the Honor Committee.

Important list operations

• the_list.append( v )

• Appends v to end of the_list

• the_list.count( v )

• Returns the number of occurrences of v in the_list

• the_list.remove( v )

• Removes first occurence of v from the_list

• the_list.index( v )

• Index of first occurrence of v in the_list

• list3 = list1 + list2

• Concatenates list1 and list2 to make list3

---

Terminology

• Explicit for my purposes means physically entered.

• i.e. means that is.

• e.g. means for example.

• Increment means add.

• Decrement means subtract.

• The additive inverse of a number x, is –x.

• The value of x / y is called a quotient.

• A number x is evenly divisible by a number y, if the remainder of x divided by y is zero. The % is the Python remainder operator.

• The terms dataset and table are synonymous. They are lists of lists. The standard view is they are lists of rows, where each row is a list of column values. The individual column values are called cells.
