A Tour of the Module itertools

Explore Python's powerful `itertools` module through this 46-minute conference talk that systematically examines all 20 tools available for efficient iterable manipulation. Learn how to categorize itertools functions into five distinct groups: combinatorial, reshaping, infinite, filtering, and complementary iterables. Discover practical usage examples for each category and understand when to apply specific itertools functions in your Python code. Master the art of writing memory-efficient Python code by leveraging iterables effectively, including the often-overlooked `tee` function. Gain proficiency in this essential Python standard library module through clear explanations and real-world applications presented at EuroPython 2025.
