PCEP Computer Programming and Python Fundamentals Practice Question

Exhibit

Refer to the exhibit.
{
  "name": "Alice",
  "age": 30,
  "city": "New York",
  "languages": ["Python", "Java"]
}
--- End of exhibit ---

The above JSON is loaded into a Python dictionary named data using json.load(). A developer writes:

print(data['languages'][1][:3])

What is printed?

⚠ Common exam trap

The PCEP exam often tests the combination of list indexing and string slicing, where candidates may forget that slicing returns a substring of the specified length, not the full string, or may misidentify the zero-based index of the list element.

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

Jav

The JSON data is loaded into a Python dictionary. The key 'languages' maps to a list of strings. Indexing with [1] retrieves the second element, which is 'Java'. Then slicing with [:3] extracts the first three characters, resulting in 'Jav'. Therefore, option B is correct.
