data?Which of the following Python code snippets correctly initializes the first sliding window of size 4 over a list named data?
easy📝 Syntax Q3 of 15
Step-by-Step Solution
Solution:
Step 1: Understand Python slicing for window initialization
Python slicing data[0:4] creates a window of exactly size 4 starting from the beginning.Step 2: Confirm correct option creates a window of size 4
data[0:4] covers 4 elements; data[1:4] covers 3 elements (indices 1,2,3); data[:3] covers 3 elements (0,1,2); All of the above is incorrect.Final Answer:
window = data[0:4] -> Option BQuick Check:
Python slices with length 4 = valid windows [OK]
Quick Trick: Python slice [start:end] covers end-start elements [OK]
Common Mistakes:
- Off-by-one errors in slice indices
- Confusing slice indices and window size
