langdetect
![Build Status](https://travis-ci.org/Mimino666/langdetect.svg?branch=master)
Port of language-detection (version from 03/03/2014) library to Python.
Installation
$ pip install langdetect
Supported Python versions 2.6, 2.7, 3.x.
Basic usage
To detect the language of the text:
>>> from langdetect import detect
>>> detect("War doesn't show who's right, just who's left.")
'en'
>>> detect("Ein, zwei, drei, vier")
'de'
To find out the probabilities for the top languages:
>>> from langdetect import detect_langs
>>> detect_langs("Otec matka syn.")

IMPORTANT
Language detection algorithm is non-deterministic, which means that if you try to run it on a text which is either too short or too ambiguous, you might get different results everytime you run it.
To enforce consistent results, call following code before the first language detection:
from langdetect import DetectorFactory
DetectorFactory.seed = 0
More information
This library is a direct port of language-detection from Java to Python. All the classes and methods (even unit tests) are unchanged, so for more information see the project's website or wiki.
