September 11, 2025 - The step option allows you to skip entries, change the order, or choose elements at precise intervals. my_list = [10, 20, 30, 40, 50, 60, 70, 80, 90, 100] # Example 1: Skipping Elements sliced_list = my_list[1:8:3] print(sliced_list)

August 21, 2025 - # A sequence (list of numbers) numbers = [10, 20, 30, 40, 50, 60] # Slice from index 1 to 4 (stop is exclusive) result = numbers[1:4] print(result) #output [20, 30, 40] 👉 Here, start = 1 (20) and stop = 4 (excludes index 4 → 50).
