Python Institute PCEP-30-02 Exam - Topic 4 Question 43 Discussion

Actual exam question for Python Institute's PCEP-30-02 exam

Question #: 43
Topic #: 4

[All PCEP-30-02 Questions]

Which of the following expressions evaluate to a non-zero result? (Select two answers.)

A2 ** 3 / A - 2

B4 / 2 * * 3 - 2

C1 * * 3 / 4 - 1

D1 * 4 // 2 ** 3

Show Suggested Answer

Suggested Answer: A, B

In Python, the ** operator is used for exponentiation, the / operator is used for floating-point division, and the // operator is used for integer division. The order of operations is parentheses, exponentiation, multiplication/division, and addition/subtraction. Therefore, the expressions can be evaluated as follows:

A) 2 ** 3 / A - 2 = 8 / A - 2 (assuming A is a variable that is not zero or undefined) B. 4 / 2 * * 3 - 2 = 4 / 8 - 2 = 0.5 - 2 = -1.5 C. 1 * * 3 / 4 - 1 = 1 / 4 - 1 = 0.25 - 1 = -0.75 D. 1 * 4 // 2 ** 3 = 4 // 8 = 0

Only expressions A and B evaluate to non-zero results.

B is definitely non-zero!

D looks like it could be zero too.

I think option D could be tricky because of the floor division; I need to double-check how that interacts with the exponentiation.

I practiced a similar question where we had to evaluate expressions, and I remember that division by zero leads to issues, so I hope none of these have that problem.

I'm not sure about option A; I feel like it could be zero if A is 2, but I can't remember if it could also be non-zero with a different value for A.

I think option B might evaluate to a non-zero result since 4 divided by 2 is 2, and then 2 to the power of 3 is 8, so 8 minus 2 should be 6.

I've got a strategy - I'll evaluate each expression and keep track of the ones that result in a non-zero value.

I'm a bit confused by the double asterisks. I'll need to review how that operator works before answering.

I'm pretty confident I know how to solve this. The key is to focus on the exponents and division first.

Hmm, this looks tricky. I'll need to carefully evaluate the order of operations for each expression.

Hmm, this looks like some kind of coding question. I'm not much of a programmer, but I think the expressions in C and D look a bit more straightforward.

The expressions in A and B seem to have some weird operators, like double asterisks and double forward slashes. I'm not sure what those mean, but I'll give it a shot.
