# editdistance | ||
|
||
Fast implementation of the edit distance (Levenshtein distance). | ||
|
||
This library simply implements [Levenshtein distance](http://en.wikipedia.org/wiki/Levenshtein_distance) with C++ and Cython. | ||
|
||
The algorithm used in this library is proposed by | ||
[Heikki Hyyrö, "Explaining and extending the bit-parallel approximate string matching algorithm of Myers", (2001)](http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.19.7158&rep=rep1&type=pdf) | ||

||
## Binary wheels | ||
|
||
Thanks to [pypa/cibuildwheel](https://github.com/pypa/cibuildwheel) | ||
There are binary wheels on Linux, Mac OS, and Windows. | ||
|
||
## Install | ||
|
||
You can install via pip: | ||
|
||
```bash | ||
pip install editdistance | ||
``` | ||
|
||
|
||
## Usage | ||
|
||
It's quite simple: | ||
|
||
```python | ||
import editdistance | ||
editdistance.eval('banana', 'bahama') | ||
# 2L | ||
``` | ||
|
||
|
||
# Simple Benchmark | ||
|
||
With IPython, I tried several libraries: | ||
|
||
* [pyxDamerauLevenshtein](https://pypi.python.org/pypi/pyxDamerauLevenshtein) | ||
* [pylev](https://pypi.python.org/pypi/pylev) | ||
* [python-Levenshtein](https://pypi.python.org/pypi/python-Levenshtein) | ||
|
||
On Python 2.7.5: | ||
|
||
```python | ||
a = 'fsffvfdsbbdfvvdavavavavavava' | ||
b = 'fvdaabavvvvvadvdvavavadfsfsdafvvav' | ||
import pylev | ||
timeit pylev.levenshtein(a, b) | ||
# 100 loops, best of 3: 7.48 ms per loop | ||
|
||
from pyxdameraulevenshtein import damerau_levenshtein_distance | ||
timeit damerau_levenshtein_distance(a, b) | ||
# 100000 loops, best of 3: 11.4 µs per loop | ||
|
||
timeit editdistance.eval(a, b) # my library | ||
# 100000 loops, best of 3: 3.5 µs per loop | ||
|
||
import Levenshtein | ||
|
||
timeit Levenshtein.distance(a, b) | ||
# 100000 loops, best of 3: 3.21 µs per loop | ||
``` | ||
|
||
## Distance with Any Object | ||
|
||
Above libraries only support strings. | ||
But Sometimes other type of objects such as list of strings(words). | ||
I support any iterable, only requires hashable object of it: | ||
|
||
```python | ||
Levenshtein.distance(['spam', 'egg'], ['spam', 'ham']) | ||
# --------------------------------------------------------------------------- | ||
# TypeError Traceback (most recent call last) | ||
# <ipython-input-22-3e0b30d145ac> in <module>() | ||
# ----> 1 Levenshtein.distance(['spam', 'egg'], ['spam', 'ham']) | ||
# | ||
# TypeError: distance expected two Strings or two Unicodes | ||
|
||
editdistance.eval(['spam', 'egg'], ['spam', 'ham']) | ||
# 1L | ||
``` | ||
|
||
So if object's hash is same, it's same. | ||
You can provide `__hash__` method to your object instances. | ||
|
||
Enjoy! | ||
