Python's standard library is great until you need a sorted collections type. Many will attest that you can get really far without one, but the moment you **really need** a sorted list, sorted dict, or sorted set, you're faced with a dozen different implementations, most using C-extensions without great documentation and benchmarking. In Python, we can do better. And we can do it in pure-Python! .. code-block:: python >>> from sortedcontainers import SortedList >>> sl = SortedList(['e', 'a', 'c', 'd', 'b']) >>> sl SortedList(['a', 'b', 'c', 'd', 'e']) >>> sl *= 10_000_000 >>> sl.count('c') 10000000 >>> sl[-3:] ['e', 'e', 'e'] >>> from sortedcontainers import SortedDict >>> sd = SortedDict({'c': 3, 'a': 1, 'b': 2}) >>> sd SortedDict({'a': 1, 'b': 2, 'c': 3}) >>> sd.popitem(index=-1) ('c', 3) >>> from sortedcontainers import SortedSet >>> ss = SortedSet('abracadabra') >>> ss SortedSet(['a', 'b', 'c', 'd', 'r']) >>> ss.bisect_left('c') 2 All of the operations shown above run in faster than linear time. The above demo also takes nearly a gigabyte of memory to run. When the sorted list is multiplied by ten million, it stores ten million references to each of "a" through "e". Each reference requires eight bytes in the sorted container. That's pretty hard to beat as it's the cost of a pointer to each object. It's also 66% less overhead than a typical binary tree implementation (e.g. Red-Black Tree, AVL-Tree, AA-Tree, Splay-Tree, Treap, etc.) for which every node must also store two pointers to children nodes. `Sorted Containers`_ takes all of the work out of Python sorted collections - making your deployment and use of Python easy. There's no need to install a C compiler or pre-build and distribute custom extensions. Performance is a feature and testing has 100% coverage with unit tests and hours of stress. .. _`Sorted Containers`: http://www.grantjenks.com/docs/sortedcontainers/ .. _`sorted collections library`: http://www.grantjenks.com/docs/sortedcontainers/ Testimonials ------------ **Alex Martelli**, `Fellow of the Python Software Foundation`_ "Good stuff! ... I like the `simple, effective implementation`_ idea of splitting the sorted containers into smaller "fragments" to avoid the O(N) insertion costs." **Jeff Knupp**, `author of Writing Idiomatic Python and Python Trainer`_ "That last part, "fast as C-extensions," was difficult to believe. I would need some sort of `Performance Comparison`_ to be convinced this is true. The author includes this in the docs. It is." **Kevin Samuel**, `Python and Django Trainer`_ I'm quite amazed, not just by the code quality (it's incredibly readable and has more comment than code, wow), but the actual amount of work you put at stuff that is *not* code: documentation, benchmarking, implementation explanations. Even the git log is clean and the unit tests run out of the box on Python 2 and 3. **Mark Summerfield**, a short plea for `Python Sorted Collections`_ Python's "batteries included" standard library seems to have a battery missing. And the argument that "we never had it before" has worn thin. It is time that Python offered a full range of collection classes out of the box, including sorted ones. `Sorted Containers`_ is used in popular open source projects such as: `Zipline`_, an algorithmic trading library from Quantopian; `Angr`_, a binary analysis platform from UC Santa Barbara; `Trio`_, an async I/O library; and `Dask Distributed`_, a distributed computation library supported by Continuum Analytics. .. _`Fellow of the Python Software Foundation`: https://en.wikipedia.org/wiki/Alex_Martelli .. _`simple, effective implementation`: http://www.grantjenks.com/docs/sortedcontainers/implementation.html .. _`author of Writing Idiomatic Python and Python Trainer`: https://jeffknupp.com/ .. _`Python and Django Trainer`: https://www.elephorm.com/formateur/kevin-samuel .. _`Python Sorted Collections`: http://www.qtrac.eu/pysorted.html .. _`Zipline`: https://github.com/quantopian/zipline .. _`Angr`: https://github.com/angr/angr .. _`Trio`: https://github.com/python-trio/trio .. _`Dask Distributed`: https://github.com/dask/distributed Features -------- - Pure-Python - Fully documented - Benchmark comparison (alternatives, runtimes, load-factors) - 100% test coverage - Hours of stress testing - Performance matters (often faster than C implementations) - Compatible API (nearly identical to older blist and bintrees modules) - Feature-rich (e.g. get the five largest keys in a sorted dict: d.keys()[-5:]) - Pragmatic design (e.g. SortedSet is a Python set with a SortedList index) - Developed on Python 3.7 - Tested on CPython 2.7, 3.2, 3.3, 3.4, 3.5, 3.6, 3.7 and PyPy, PyPy3 .. image:: https://api.travis-ci.org/grantjenks/python-sortedcontainers.svg?branch=master :target: http://www.grantjenks.com/docs/sortedcontainers/ .. image:: https://ci.appveyor.com/api/projects/status/github/grantjenks/python-sortedcontainers?branch=master&svg=true :target: http://www.grantjenks.com/docs/sortedcontainers/ Quickstart ---------- Installing `Sorted Containers`_ is simple with `pip `_:: $ pip install sortedcontainers You can access documentation in the interpreter with Python's built-in `help` function. The `help` works on modules, classes and methods in `Sorted Containers`_. .. code-block:: python >>> import sortedcontainers >>> help(sortedcontainers) >>> from sortedcontainers import SortedDict >>> help(SortedDict) >>> help(SortedDict.popitem) Documentation ------------- Complete documentation including performance comparisons is available at http://www.grantjenks.com/docs/sortedcontainers/ User Guide ..........
