Actual exam question for Python Institute's PCEP-30-02 exam
Question #: 27
Topic #: 1
[All PCEP-30-02 Questions]

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

Show Suggested Answer Hide 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.

Whoa, hold up! Is this a coding quiz or a magic trick? I'm seeing double asterisks, and that's not even a thing, right?

B and D, easy peasy. Though I think the double asterisks are a bit overkill, don't you think?

D for sure, but I'm stumped on the other one. Gotta double-check my math skills.
