Many will attest that you can get really far without one, but the moment\nyou **really need** a sorted list, sorted dict, or sorted set, you're faced\nwith a dozen different implementations, most using C-extensions without great\ndocumentation and benchmarking.\n\nIn Python, we can do better. And we can do it in pure-Python!\n\n.. code-block:: python\n\n    \u003e\u003e\u003e from sortedcontainers import SortedList\n    \u003e\u003e\u003e sl = SortedList(['e', 'a', 'c', 'd', 'b'])\n    \u003e\u003e\u003e sl\n    SortedList(['a', 'b', 'c', 'd', 'e'])\n    \u003e\u003e\u003e sl *= 10_000_000\n    \u003e\u003e\u003e sl.count('c')\n    10000000\n    \u003e\u003e\u003e sl[-3:]\n    ['e', 'e', 'e']\n    \u003e\u003e\u003e from sortedcontainers import SortedDict\n    \u003e\u003e\u003e sd = SortedDict({'c': -3, 'a': 1, 'b': 2})\n    \u003e\u003e\u003e sd\n    SortedDict({'a': 1, 'b': 2, 'c': -3})\n    \u003e\u003e\u003e sd.popitem(index=-1)\n    ('c', -3)\n    \u003e\u003e\u003e from sortedcontainers import SortedSet\n    \u003e\u003e\u003e ss = SortedSet('abracadabra')\n    \u003e\u003e\u003e ss\n    SortedSet(['a', 'b', 'c', 'd', 'r'])\n    \u003e\u003e\u003e ss.bisect_left('c')\n    2\n\nAll of the operations shown above run in faster than linear time. The above\ndemo also takes nearly a gigabyte of memory to run. When the sorted list is\nmultiplied by ten million, it stores ten million references to each of \"a\"\nthrough \"e\". Each reference requires eight bytes in the sorted\ncontainer. That's pretty hard to beat as it's the cost of a pointer to each\nobject. It's also 66% less overhead than a typical binary tree implementation\n(e.g. Red-Black Tree, AVL-Tree, AA-Tree, Splay-Tree, Treap, etc.) for which\nevery node must also store two pointers to children nodes.\n\n`Sorted Containers`_ takes all of the work out of Python sorted collections -\nmaking your deployment and use of Python easy. There's no need to install a C\ncompiler or pre-build and distribute custom extensions. Performance is a\nfeature and testing has 100% coverage with unit tests and hours of stress.\n\n.. _`Sorted Containers`: http://www.grantjenks.com/docs/sortedcontainers/\n.. _`sorted collections library`: http://www.grantjenks.com/docs/sortedcontainers/\n\nTestimonials\n------------\n\n**Alex Martelli**, `Fellow of the Python Software Foundation`_\n\n\"Good stuff! ... I like the `simple, effective implementation`_ idea of\nsplitting the sorted containers into smaller \"fragments\" to avoid the O(N)\ninsertion costs.\"\n\n**Jeff Knupp**, `author of Writing Idiomatic Python and Python Trainer`_\n\n\"That last part, \"fast as C-extensions,\" was difficult to believe. I would need\nsome sort of `Performance Comparison`_ to be convinced this is true. The author\nincludes this in the docs. It is.\"\n\n**Kevin Samuel**, `Python and Django Trainer`_\n\nI'm quite amazed, not just by the code quality (it's incredibly readable and\nhas more comment than code, wow), but the actual amount of work you put at\nstuff that is *not* code: documentation, benchmarking, implementation\nexplanations. Even the git log is clean and the unit tests run out of the box\non Python 2 and 3.\n\n**Mark Summerfield**, a short plea for `Python Sorted Collections`_\n\nPython's \"batteries included\" standard library seems to have a battery\nmissing. And the argument that \"we never had it before\" has worn thin. It is\ntime that Python offered a full range of collection classes out of the box,\nincluding sorted ones.\n\n`Sorted Containers`_ is used in popular open source projects such as:\n`Zipline`_, an algorithmic trading library from Quantopian; `Angr`_, a binary\nanalysis platform from UC Santa Barbara; `Trio`_, an async I/O library; and\n`Dask Distributed`_, a distributed computation library supported by Continuum\nAnalytics.\n\n.. _`Fellow of the Python Software Foundation`: https://en.wikipedia.org/wiki/Alex_Martelli\n.. _`simple, effective implementation`: http://www.grantjenks.com/docs/sortedcontainers/implementation.html\n.. _`author of Writing Idiomatic Python and Python Trainer`: https://jeffknupp.com/\n.. _`Python and Django Trainer`: https://www.elephorm.com/formateur/kevin-samuel\n.. _`Python Sorted Collections`: http://www.qtrac.eu/pysorted.html\n.. _`Zipline`: https://github.com/quantopian/zipline\n.. _`Angr`: https://github.com/angr/angr\n.. _`Trio`: https://github.com/python-trio/trio\n.. _`Dask Distributed`: https://github.com/dask/distributed\n\nFeatures\n--------\n\n- Pure-Python\n- Fully documented\n- Benchmark comparison (alternatives, runtimes, load-factors)\n- 100% test coverage\n- Hours of stress testing\n- Performance matters (often faster than C implementations)\n- Compatible API (nearly identical to older blist and bintrees modules)\n- Feature-rich (e.g. get the five largest keys in a sorted dict: d.keys()[-5:])\n- Pragmatic design (e.g. SortedSet is a Python set with a SortedList index)\n- Developed on Python 3.10\n- Tested with CPython 3.7, 3.8, 3.9, 3.10, 3.11, 3.12 and PyPy3\n- Tested on Linux, Mac OSX, and Windows\n\n.. image:: https://github.com/grantjenks/python-sortedcontainers/workflows/integration/badge.svg\n   :target: http://www.grantjenks.com/docs/sortedcontainers/\n\n.. image:: https://github.com/grantjenks/python-sortedcontainers/workflows/release/badge.svg\n   :target: http://www.grantjenks.com/docs/sortedcontainers/\n\nQuickstart\n----------\n\nInstalling `Sorted Containers`_ is simple with `pip\n\u003chttps://pypi.org/project/pip/\u003e`_::\n\n    $ pip install sortedcontainers\n\nYou can access documentation in the interpreter with Python's built-in `help`\nfunction.
