PCEP Control Flow, Loops, Lists and Logic Practice Question
This PCEP practice question tests your understanding of control flow, loops, lists and logic. 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.
A team observes that the following code prints 'Found' even when the item is not in the list. Code: for item in mylist: if item == target: print('Found'); break; else: print('Not found'). Which modification ensures it correctly prints 'Not found' only if the item is not present?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Align the else with the for statement (for-else construct)
Option D is correct because the original code uses a for-else construct where the else block executes after the loop completes normally (i.e., without a break). However, the code has a syntax error: the else is incorrectly indented as part of the if statement, causing it to execute on every iteration when the condition is false. Aligning the else with the for statement (for-else construct) ensures the else block runs only if the loop finishes without hitting a break, which occurs when the item is not found.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Move else inside the if block
Why it's wrong here
This would not change the logic; else still prints for each non-matching item.
✗
Replace break with continue
Why it's wrong here
continue does not terminate loop; else clause will always execute.
✗
Use a flag variable to track found status
Why it's wrong here
This works but is not the most Pythonic; for-else is preferred.
✓
Align the else with the for statement (for-else construct)
Why this is correct
Correct: for-else executes else only if no break occurred.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Python Institute often tests the for-else construct by presenting code where the else is incorrectly indented under the if, leading candidates to think the else belongs to the if statement, when in fact the intended behavior requires the else to be aligned with the for.
Detailed technical explanation
How to think about this question
The for-else construct in Python is a unique feature where the else clause executes only if the loop terminates normally (i.e., without a break). Under the hood, Python's bytecode for a for loop includes a SETUP_LOOP instruction that tracks whether a break occurred; if not, the else block is executed. This is particularly useful in search algorithms where you want to confirm absence without a flag, and it avoids the common C-style pattern of setting a found variable.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
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.

What is the correct answer to this question?
The correct answer is: Align the else with the for statement (for-else construct) — Option D is correct because the original code uses a for-else construct where the else block executes after the loop completes normally (i.e., without a break). However, the code has a syntax error: the else is incorrectly indented as part of the if statement, causing it to execute on every iteration when the condition is false.
