kandi X-RAY | pytrie Summary

pytrie is a Python library typically used in Artificial Intelligence, Natural Language Processing applications. pytrie has no bugs, it has no vulnerabilities, it has build file available and it has low support. However pytrie has a Non-SPDX License. You can install using 'pip install pytrie' or download it from GitHub, PyPI.

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. Documentation is available at Read the Docs.

It's slow due to how Python debuggers work and how imports work. Importing in Python is literally executing the code in the module. Executing code under a debugger is inherently slower as every step of the execution has to pass through the debugger to see if e.g. a breakpoint is hit.

The only way for this to go faster is for the debuggers to be faster (the Python extension for VS Code is looking at pulling in some debugger speed improvements, but there's no timeline on when those will land and initially they will only be for Python 3.7).

It looks like the issue is that this datrie package supports at most 255 values for characters in the keyset: https://github.com/pytries/datrie/blob/master/libdatrie/datrie/alpha-map.h#L59

I recommend using marisa_trie::RecordTrie from here: https://pypi.python.org/pypi/marisa-trie

Unfortunately it's a static data structure, so you cannot modify it after building, but it fully support unicode, serialization to disk, and all sorts of value types.

Patricia/Radix tree/tries seem to be the answer. I found them by searching for algorithms for looking up routing tables.

There is a python implementation here.

A little later: I now have this working fine in Ruby:
