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 function arguments are true? (Select exactly 3)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Keyword arguments can be passed in any order, regardless of their position in the function definition.
Option A is true: default arguments are evaluated at function definition time. Option B is false: keyword arguments can be used in any order as long as they are after positional. Option C is true: *args collects extra positional arguments into a tuple. Option D is true: **kwargs collects extra keyword arguments into a dictionary. Option E is false: you cannot mix *args and **kwargs arbitrarily; *args must come before **kwargs in definition.
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.
✓
Keyword arguments can be passed in any order, regardless of their position in the function definition.
Why this is correct
Keyword arguments can be specified in any order after positional arguments.

✓
Using **kwargs allows passing a variable number of keyword arguments.
Why this is correct
**kwargs collects extra keyword arguments into a dictionary.

✗
The *args parameter must always come after **kwargs in a function definition.
Why it's wrong here
*args must come before **kwargs.
✓
Using *args in a function definition allows passing a variable number of positional arguments.
Why this is correct
*args collects extra positional arguments into a tuple.
Related concept

✓
Default arguments are evaluated once when the function is defined, not each time it is called.
Why this is correct
Default values are evaluated at definition time.

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.
