Trie data structure implementation.

Project Description

pytrie is a Python library implementing a trie data structure.

Trie data structure, also known as radix or prefix tree, is an ordered tree associating keys to values where all the descendants of a node have a common prefix (associated with that node).

The trie module contains Trie, CharTrie and StringTrie classes each implementing a mutable mapping interface, i.e. interface of the dictionary. As such, in most circumstances, Trie could be used as a drop-in replacement for a dict. Obviously the prefix nature of the data structure is what gives it its strengths.


  • A full mutable mapping implementation.
  • Supports iterating over as well as deleting a subtrie.
  • Supports prefix checking as well as shortest and longest prefix look-up.
  • Extensible for any kind of user-defined keys.
