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
  • 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
