What You’ll Practice#

1. Writing for loops to iterate through lists and dictionaries
2. Building accumulator patterns — totals, filtered lists, summary dicts
3. Combining loops and branching for customer classification
4. Writing while loops with appropriate stopping conditions
5. Using break and continue to control loop execution

Learning Objectives#

By completing this notebook you will be able to:

• Write for loops that iterate through lists and dictionaries
• Apply the accumulator pattern to build totals, filtered lists, and summary dictionaries
• Combine for loops with if/elif/else blocks for data classification
• Write while loops with correct stopping conditions
• Predict the output of a loop before running it
