This page provides a browser-based dry run with source-code highlighting, auto-scroll, voice narration controls, and execution output for learning the program step by step.

Negative indexing examples Program Code

# Negative indexing examples
numbers = [10, 20, 30, 40, 50, 60]
print("List:", numbers)

# Negative indices count from end
print(f"Index -1 (last): {numbers[-1]}")
print(f"Index -2 (second last): {numbers[-2]}")
print(f"Index -3 (third last): {numbers[-3]}")
print(f"Index -6 (first): {numbers[-6]}")

# Slicing with negative indices
print(f"Last 3 elements: {numbers[-3:]}")
print(f"All except last: {numbers[:-1]}")
