A thread safe implementation of a Trie.

Project description



Poetries provides a thread-safe implementation of a Trie. While not limited, but the most common use case of a Trie is in implementing auto-completion. The collection type exposes APIs to perform the following operationsadd, find and get_all_words_with_prefix.


Python 3


pip install --upgrade poetries


from poetries.trie import Trie

trie = Trie()
trie.add('foobar')              # Adds 'foobar' to the trie
trie.find('foo')                # Returns False since the word is not present.
trie.add('bar')                 # Adds 'bar' to the trie
trie.find('bar')                # Returns True
trie.add('foob')                # Adds 'foob' to the trie
trie.add('foof')                # Adds 'foof' to the trie
arr = list(trie.prefix('foo'))  # Returns the list of words beginning with foo in a list form, ['foobar', 'foo', 'foob', 'foof']
