Python Institute Certifications Practice Exams
Study Python programming and data analytics with certification-specific questions and detailed explanations. Choose from PCEP, PCAP, PCPP1 and PCED practice packs, and connect the concepts you review with code you write and test yourself.
Try three short Python 3 questions about lists, dictionaries, and exceptions. Read the explanation after each answer.
A Python program stores scores = [8, 13, 21, 34]. What is the value of scores[1:3]?
- [8, 13]
- [13, 21]
- [13, 21, 34]
- [21, 34]
Reveal the answer
[13, 21] Python sequence indexes start at zero. A slice includes its start index and stops before its end index, so indexes 1 and 2 select 13 and 21. The original list is unchanged by this slice expression.
