Method 6: Swap using list/array Dry Run in PYTHON

Method 6: Swap using list/array is an interactive PYTHON dry run visualizer from the Io programs section. Study the source code, then use the execution controls to follow each step, variable update, highlighted line, and console output.

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.

Method 6: Swap using list/array Program Code

# Method 6: Using list/array
a = int(input("Enter first number: "))
b = int(input("Enter second number: "))

print(f"\nBefore swap: a = {a}, b = {b}")

# Swapping using list
arr = [a, b]
a = arr[1]
b = arr[0]

print(f"After swap: a = {a}, b = {b}")
