Copy String Dry Run in PYTHON

Copy String is an interactive PYTHON dry run visualizer from the Strings 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.

Copy String Program Code

# Python program to copy a string
source = "Copy Me!"

# Method 1: Direct assignment (creates reference)
destination1 = source

# Method 2: Using slicing (creates a new copy)
destination2 = source[:]

# Method 3: Using str() constructor
destination3 = str(source)

print("Source:", source)
print("Copied (assignment):", destination1)
print("Copied (slicing):", destination2)
print("Copied (constructor):", destination3)

# Compare the copied contents
print("Do source and destination2 have equal contents?", source == destination2)
