Collections constitute vital components in Python programming, catering to diverse use cases spanning data representation, algorithm implementation, and system organization. Effectively navigating these entities demands proficient command over iteration techniques, empowering developers to traverse, filter, transform, and aggregate information intelligently.

This tutorial elucidates essential iteration approaches applicable to popular Python collections, namely lists, tuples, sets, dictionaries, and generators.

Prerequisites

Familiarity with Python basics, notably variables, strings, arithmetic operators, conditional statements, loops, and standard library modules, lays groundwork for digesting subsequent material.

List Iteration

Traverse list elements sequentially, consuming index positions or exploiting dedicated iterator protocols.

# Index-based approach
my_list = [1, 2, 3, 4, 5]
index = 0
while index < len(my_list):
current_elem = my_list[index]…
