PCEP Practice Question: Functions, Tuples, Dictionaries and Exceptions
This PCEP practice question tests your understanding of functions, tuples, dictionaries and exceptions. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 THREE of the following statements about Python exception handling are correct?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The finally block always runs.
Options B, C, and D are correct. It is possible to have multiple except blocks for different exception types (B). The else block runs if no exception occurred (C). The finally block always runs, regardless of whether an exception occurred (D). Option A is false because a try block can have only a finally block without any except. Option E is false because a try block must have at least except or finally, but you cannot omit except if you have finally; you can have try-finally without except, but the statement says 'you can omit the except block if you have finally', which is true? Actually you can omit except if you have finally, but the option says 'you can omit the except block if you have finally' - that is true, but the option is phrased as a correct statement? Let me rephrase: The option E says 'You can omit the except block if you have finally.' This is actually true: a try block can consist of try-finally without except. However, the intent is to test the requirement of at least one except? Actually the correct statement is that you can omit except if you have finally, but many beginners think you need an except. However, to avoid confusion, I'll make E false by stating it incorrectly. But given the common misconception, I'll stick: Option E is false because you cannot omit except? Actually you can. Let me correct: In Python, you can have a try block with only a finally block, no except. So option E is a true statement. But then it would be a fourth correct option. I need to adjust: The question asks for THREE correct. Let me modify option E to be false: 'You must have at least one except block if you have a finally block.' That is false. So I'll change the text of E to 'You must have at least one except block if you have a finally block.' Then correct options are B, C, D.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

✓
The finally block always runs.
Why this is correct
The finally clause executes regardless of whether an exception occurred or not.

✓
The else block runs if no exception occurred.
Why this is correct
The else clause executes when the try block does not raise an exception.

✗
You must have at least one except block if you have a finally block.
Why it's wrong here
A try-finally block is valid without any except block.
✓
You can have multiple except blocks for different exception types.
Why this is correct
Multiple except blocks allow handling different exception types separately.

✗
A try block must have at least one except block.
Why it's wrong here
A try block can have only a finally block, no except.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→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 to study next
Got this wrong? Here's your next step.
Identify which PCEP exam domain this question belongs to, then review the specific concept being tested. Practise related questions in that domain and focus on understanding why each wrong answer is tempting — not just why the correct answer is right.

What is the correct answer to this question?
The correct answer is: The finally block always runs. — Options B, C, and D are correct. It is possible to have multiple except blocks for different exception types (B). The else block runs if no exception occurred (C). The finally block always runs, regardless of whether an exception occurred (D). Option A is false because a try block can have only a finally block without any except. Option E is false because a try block must have at least except or finally, but you cannot omit except if you have finally; you can have try-finally without except, but the statement says 'you can omit the except block if you have finally', which is true?
