The correct answer is Option B, which uses `items = data.split(", ")` and then `second = items[1]`. This works because the `split()` method in Python divides a string into a list based on the specified delimiter, and by passing the exact delimiter `", "` (comma followed by a space), you match the input format precisely, so each resulting item is already clean of leading or trailing spaces. On the Certified Associate Python Programmer PCAP exam, this tests your understanding of string methods and list indexing, a common task when you need to split a comma-separated string and extract an item. A frequent trap is using `split(",")` without the space, which leaves whitespace attached to items, or using `split()` with no argument, which splits on any whitespace and includes commas in the items. To remember: always match the delimiter exactly as it appears in the data—here, the space after the comma is part of the separator, not the item.
PCAP Strings Practice Question
This PCAP practice question tests your understanding of strings. 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 developer wrote a script that processes user input. The script expects a string containing a list of comma-separated values. The user enters "apple, banana, cherry, date". The script uses split() to separate the items. Which code correctly extracts the second item without leading/trailing spaces?
Why wrong: Splits on whitespace, which results in items containing commas, e.g., 'apple,'.
B
items = data.split(", "); second = items[1]
Correctly splits on comma-space, directly obtaining the second item without extra spaces.
C
items = data.split(","); second = items[1].strip()
Why wrong: This works but strips extra spaces; however, the input has a space after the comma, so using strip is unnecessary but acceptable. However, B is more direct for this input.
D
items = data.split(","); second = items[2].strip()
Why wrong: Index 2 retrieves the third item ('cherry'), not the second.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
items = data.split(", "); second = items[1]
Option B correctly splits on ', ' which matches the input format, returning the second item without extra spaces. Option A also works but is less direct. Option C splits on whitespace, including commas in items. Option D gets the third item.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
