more-itertools is a Python library providing additional routines, building blocks, and recipes for working with iterables, extending the standard library's itertools module. It offers functions for grouping, chunking, windowing, peeking, and other common iteration patterns.

Use cases

• chunk a list into fixed-size batches
• peek at the next item of an iterator without consuming it
• split an iterable into groups based on a condition
• window over a sequence with sliding windows
• flatten nested iterables
• cycle through iterables with limits

When to choose

• you need iteration utilities beyond Python's built-in itertools
• you want well-tested, pure-Python iterable helpers with zero dependencies
• you frequently chunk, group, or window sequences

When to avoid

• you only need basic itertools functions already in the standard library
• you need C-speed performance for hot loops where hand-rolled code is faster
• your project targets a non-Python language
