Language detection with python

[S.Selvam]

Hi all,

I am trying for language detection in python.I just need to check whether
the input text is english or not.

1)I tried nltk's stopwords and compared with input text,but only with little
success.

2)Used oice.langdet for language detection,which uses bi-gram approach.It is
also inefficient.

I need a best way to detect english text .

I welcome your suggestions ...
