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.

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.
