All-in-one: Create, modify, traverse, analyze Dry Run in PYTHON

All-in-one: Create, modify, traverse, analyze is an interactive PYTHON dry run visualizer from the Lists 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.

All-in-one: Create, modify, traverse, analyze Program Code

# Comprehensive list operations demo
# Step 1: Create list
data = [5, 12, 8, 3, 15, 7, 22, 9]
print("Original:", data)

# Step 2: Add elements
data.append(18)
data.insert(2, 25)
print("After append & insert:", data)

# Step 3: Remove elements
data.remove(8)
popped = data.pop(4)
print(f"Removed 8, popped {popped}:", data)

# Step 4: Analyze
print(f"\nLength: {len(data)}")
print(f"Sum: {sum(data)}")
print(f"Average: {sum(data)/len(data):.2f}")
print(f"Max: {max(data)}, Min: {min(data)}")

# Step 5: Filter & reverse
evens = [x for x in data if x % 2 == 0]
print(f"Even numbers: {evens}")
print(f"Reversed: {data[::-1]}")
