Module 026: Working with Collections (itertools, zip, enumerate)

Phase: 3. Data Structures
Estimated Time: 2 hours
Milestone: No

Overview

Learn powerful tools for working with collections: zip() for combining iterables, enumerate() for indexed iteration, and the itertools module for advanced iteration patterns.

Topics

• zip() to combine iterables
• enumerate() for indexed iteration
• itertools overview: count, cycle, repeat, chain, product, permutations, combinations
• Practical examples

Learning Objectives

• Use zip() to iterate over multiple sequences in parallel
• Use enumerate() with a start parameter
• Leverage common itertools functions for iteration patterns
• Apply these tools to real-world problems

Prerequisites

• Modules 000–025
