A pure Python implementation of the trie data structure.

Project description

# pytrie

pytrie is a a pure Python 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.

To install run:

pip install pytrie

Documentation is available at [Read the Docs](https://pytrie.readthedocs.io/).
