Version 1.9.1 2017, January 9

Clever, quick iterator functions that make your smile whiter.

This will work with versions of Python 2.6+ and 3.2+. The tests also pass with recent Pypy and Jython releases.

## Functions

There are many functions that process data from iterators in efficient ways.

• yany – Extended version of the builtin any, test if any values are true
• yall – Extended version of the builtin all, test if all values are true
• ylen – Complete an iterator and get number of values
• first – Get the first value from an iteraterable
• last – Get the final value from an iteraterable
• head – Get the first values from an iteraterable
• tail – Get the last values from an iteraterable
• minmax – Find the minimum and maximum values from an iterable
• minmedmax – Find the minimum, median, and maximum values from an iterable
• isiter – Test if an object is iterable, but not a string type
• sequence – Efficient copy of non sequence data
• repeat – Efficient lazy copy of non sequence data

## Iterators

There are several iterators that wrap an existing iterator and process it’s output.

• call – Iterator that works with mixed callable types
• percent – Iterator that skips a percentage of values
• flat – Iterator of values from a iterable of iterators
• chunk – Iterator of lists with a fixed size from iterable
• key – Iterator of pairs of key result and original values
• unique – Iterate only the unique values
• duplicates – Iterate only the duplicated values

## Keys

Utility functions that are useful to use as a key argument

• formatter – Create a function that formats given values into strings
• numeric – Split a string into string and integer sections
• getter – Shorthand for attrgetter, itemgetter, and methodcaller operators
