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.

I’m confused about option C. I think it might evaluate to zero, but I can't recall the exact calculations.

I practiced a similar question last week, and I remember that division and exponentiation can lead to tricky results. I’m leaning towards A and B.

I'm not entirely sure, but I remember something about exponentiation having a higher precedence. Maybe option D could also be non-zero?

I think option B might be one of the answers since it looks like it evaluates to a positive number after the operations.
