This PCEP practice question tests your understanding of data types, variables, basic i/o and operators. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Refer to the exhibit. ```python a = 10 b = 3 print(a / b) print(a // b) print(a % b) ```
Refer to the exhibit. Which of the following shows the correct output?
Refer to the exhibit. ```python a = 10 b = 3 print(a / b) print(a // b) print(a % b) ```
3.3333333333333335 4 1
Why wrong: Floor division should be 3, not 4.
3.3333333333333335 3 1
Correct outputs.
3.0 3.0 1.0
Why wrong: Floor division and modulus return int when both ints.
3 3 0
Why wrong: Division yields float, and remainder is 1.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
3.3333333333333335 3 1
Option B is correct because the code `print(10/3)` performs floating-point division in Python 3, yielding `3.3333333333333335`; `print(10//3)` performs floor division, which truncates to the nearest integer less than or equal to the result, giving `3`; and `print(10%3)` computes the remainder of the division, which is `1`.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

Common exam traps
The trap here is that candidates often confuse the behavior of the `/` operator (which always returns a float in Python 3) with integer division from Python 2, or they misapply floor division and remainder operations, especially when dealing with positive integers.
Detailed technical explanation
In Python 3, the `/` operator always returns a float, while `//` performs floor division, returning the largest integer less than or equal to the true quotient. The `%` operator returns the remainder, which satisfies the identity `a = (a // b) * b + (a % b)`. Floating-point representation causes `10/3` to be stored as a binary approximation, leading to the trailing `5` in `3.3333333333333335` due to IEEE 754 double-precision rounding.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the PCEP exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
