Traverse list using while loop Dry Run in PYTHON

Traverse list using while loop 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.

Traverse list using while loop Program Code

# Traverse list using while loop
scores = [95, 87, 92, 78, 89, 96]
print("Scores:", scores)

# Using while loop with index
i = 0
print("\nTraversing with while loop:")
while i < len(scores):
    print(f"  Position {i}: {scores[i]}")
    i += 1

# While loop with manual break condition
j = 0
print("\nStop when score < 90:")
while j < len(scores) and scores[j] >= 90:
    print(f"  {scores[j]} is >= 90")
    j += 1
