multisplitby

multisplitby |build| |coverage|

Split an iterable into multiple using arbitrary predicates.

This package comes with a single function: multisplitby.multi_split_by.

For all lists values and predicates, the following conditions are always true:

• 1 + len(predicates) = len(list(multi_split_by(values, predicates)))
• values == itertools.chain.from_iterable(multi_split_by(values, predicates))

Normal usage with one predicate:

.. code-block:: python

values = range(4) predicates = [lambda x: 2 < x] list(map(list, multi_split_by(values, predicates))) [[0, 1, 2], [3]]

Normal usage with several predicates:

.. code-block:: python

values = range(9) predicates = [lambda x: 2 < x, lambda x: 4 < x, lambda x: 7 < x] list(map(list, multi_split_by(values, predicates))) [[0, 1, 2], [3, 4], [5, 6, 7], [8]]

If no values are given, will result in |predicates| + 1 generators, all yielding empty lists.

.. code-block:: python

values = [] predicates = [lambda x: 2 < x, lambda x: 4 < x, lambda x: 7 < x] list(map(list, multi_split_by(values, predicates))) [[], [], [], []]

If no predicates are given, will result in a single generator that yields the original list:

.. code-block:: python

values = range(4) predicates = [] list(map(list, multi_split_by(values, predicates))) [[0, 1, 2, 3]]
