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.
Which of the following expressions evaluate to True? (Choose three.)
3 ** 2 == 9
3 squared equals 9.
4.0 == 4
Float 4.0 and integer 4 are numerically equal.
10 % 3 == 0
Why wrong: 10 modulo 3 equals 1, not 0.
"Py" in "Python"
The substring 'Py' is found in 'Python'.
bool(0)
Why wrong: bool(0) returns False because 0 is considered False.
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 ** 2 == 9
Option A is correct because the exponentiation operator `**` computes 3 raised to the power of 2, which equals 9, and the `==` operator checks equality, so `3 ** 2 == 9` evaluates to `True`.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.

bool(0)
Why it's wrong here
bool(0) returns False because 0 is considered False.
Common exam traps
Cisco often tests the distinction between the modulo operator returning the remainder (not the quotient) and the falsy nature of zero, leading candidates to mistakenly think `10 % 3 == 0` or `bool(0)` evaluate to `True`.
Detailed technical explanation
In Python, the `==` operator performs value equality comparison, and for numeric types, it automatically converts integers to floats when comparing, so `4.0 == 4` returns `True` (option B). The `in` operator checks substring membership, and `"Py" in "Python"` returns `True` because "Py" is a contiguous substring starting at index 0 (option D). Understanding implicit type coercion and truthiness is critical for avoiding subtle bugs in conditional expressions.
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.
