A pure Python implementation of the trie data structure.
pytrie is a a pure Python (2 and 3) implementation of the trie data structure.
A _trie_ is an ordered tree data structure that is used to store a mapping where the keys are sequences, usually strings over an alphabet. In addition to implementing the mapping interface, tries allow finding the items for a given prefix, and vice versa, finding the items whose keys are prefixes of a given key.
pytrie runs on Python 2.7 and 3.x without modification. To install run:
pip install pytrie
Documentation is available at [Read the Docs](https://pytrie.readthedocs.io/).

- Added __bool__ (__nonzero__) and __cmp__ methods to Trie.
- Added sortedcontainers dependency.
- Converted from Mercurial to Git.
- Initial Python 3 support (thanks Dmitrijs Milajevs)
- Initial release
