A Python Wrapper for Google AJAX Language API, Uses Google Language Detection, in cases source language is not provided with the source text, Splits up text if it's longer then 4500 characters, as a limit put up by the API. Working fine for me, please let me know if i missed something.

I'm just learning.

How do you run this code? I would like to see the output.

Quick Test run/

$~/Desktop$ python recipe-576890-1.py

Write something You want to be translated to English,
Enter ctrl+c to exit

>  mucho gracias amigo
Thank you friend
> ...

So as you can see, given the original spanish text(mucho gracias amigo), it uses google language translation API to get the corresponding english translated text. if you are familiar with python, you can also download and import this recipe and can call the translate function to do the language translation yourself. See how test(...) functions uses translate(...) to translate user's input.

>>> import recipe
>>> recipe.translate(non_english_text) #Prints English transation of the param text.
