Which of the following is the correct way to initialize a sliding window of size 3 over a list named data in Python?
Awindow = data[3]
Bwindow = data[0:3]
Cwindow = data(0,3)
Dwindow = data[:]
Step-by-Step Solution
Solution:
  1. Step 1: Recall Python list slicing syntax

    To get the first 3 elements, use data[0:3], which includes indices 0, 1, and 2.
  2. Step 2: Check other options

    data(0,3) is invalid syntax, data[3] gets only one element at index 3, data[:] gets the whole list.
  3. Final Answer:

    window = data[0:3] -> Option B
  4. Quick Check:

    Slice first 3 elements = data[0:3] [OK]
Quick Trick: Use data[start:end] to slice lists in Python [OK]
Common Mistakes:
  • Using parentheses instead of brackets
  • Selecting a single element instead of a slice
  • Taking the whole list instead of a window
