Question 1
Which of the following expressions evaluate to a non-zero result? (Select two answers.)
- 2 ** 3 / A - 2
- 4 / 2 * * 3 - 2
- 1 * * 3 / 4 - 1
- 1 * 4 // 2 ** 3
Correct answer: AB
Explanation:
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 = 0Only expressions A and B evaluate to non-zero results.

Only expressions A and B evaluate to non-zero results.
Question 2
Insert the code boxes in the correct positions in order to build a line of code which asks the user for a float value and assigns it to the mass variable.
(Note: some code boxes will not be used.)
Correct answer: To work with this question, an Exam Simulator is required.
Question 3
Python Is an example of which programming language category?
- interpreted
- assembly
- compiled
- machine
Correct answer: A
Explanation:
Python is an interpreted programming language, which means that the source code is translated into executable code by an interpreter at runtime, rather than by a compiler beforehand. Interpreted languages are more flexible and portable than compiled languages, but they are also slower and less efficient. Assembly and machine languages are low-level languages that are directly executed by the hardware, while compiled languages are high-level languages that are translated into machine code by a compiler before execution.
