Python script to translate via google translate

I'm trying to learn python, so I decided to write a script that could translate something using google translate. Till now I wrote this:

import sys
from BeautifulSoup import BeautifulSoup
import urllib2
import urllib

data = {'sl':'en','tl':'it','text':'word'} 
request = urllib2.Request('http://www.translate.google.com', urllib.urlencode(data))

request.add_header('User-Agent', 'Mozilla/5.0 (Windows; U; Windows NT 5.1; it; rv:1.8.1.11) Gecko/20071127 Firefox/2.0.0.11')
opener = urllib2.build_opener()
feeddata = opener.open(request).read()
#print feeddata
soup = BeautifulSoup(feeddata)
print soup.find('span', id="result_box")
print request.get_method()

And now I'm stuck. I can't see any bugs in it, but it still doesn't work (by that I mean that the script will run, but it wont translate the word).

Does anyone know how to fix it? (Sorry for my poor English)

Yes their documentation is not so easy to uncover.

Here's what you do:

  1. In the Google Cloud Platform Console:

    1.1 Go to the Projects page and select or create a new project

    1.2 Enable billing for your project

    1.3 Enable the Cloud Translation API

    1.4 Create a new API key in your project, make sure to restrict usage by IP or other means available there.

  1. In the machine where you want to run the client:

    pip install --upgrade google-api-python-client

  1. Then you can write this to send translation requests and receive responses:

Here's the code:

import json
from apiclient.discovery import build

query='this is a test to translate english to spanish'
target_language = 'es'

service = build('translate','v2',developerKey='INSERT_YOUR_APP_API_KEY_HERE')

collection = service.translations()

request = collection.list(q=query, target=target_language)

response = request.execute()

response_json = json.dumps(response)

ascii_translation = ((response['translations'][0])['translatedText']).encode('utf-8').decode('ascii', 'ignore')

utf_translation = ((response['translations'][0])['translatedText']).encode('utf-8')

print response
print ascii_translation
print utf_translation

Google translate is meant to be used with a GET request and not a POST request. However, urrllib2 will automatically submit a POST if you add any data to your request.

The solution is to construct the url with a querystring so you will be submitting a GET.
You'll need to alter the request = urllib2.Request('http://www.translate.google.com', urllib.urlencode(data)) line of your code.

Here goes:

querystring = urllib.urlencode(data)
request = urllib2.Request('http://www.translate.google.com' + '?' + querystring )

And you will get the following output:

<span id="result_box" class="short_text">
    <span title="word" onmouseover="this.style.backgroundColor='#ebeff9'" onmouseout="this.style.backgroundColor='#fff'">
        parola
    </span>
</span>

By the way, you're kinda breaking Google's terms of service; look into them if you're doing more than hacking a little script for training.

Using requests

I strongly advise you to stay away from urllib if possible, and use the excellent requests library, which will allow you to efficiently use HTTP with Python.
