itertools

Efficient iterator combinatorics and operations for memory-efficient looping. Provides combinations, permutations, cartesian products, and chainable iterators. Use when generating all possible currency pairs, exploring trading paths, creating sequences without loading into memory, grouping sorted data, computing running accumulations, or working with infinite sequences. Ideal for combinatorial analysis and lazy iteration.
