translate method returns None

[wotanzheng]

Me again.:-)

I just write the following code and run it and get None.

import google_translate
translator = google_translate.GoogleTranslator()
print translator.translate("field managements across China, was developed to estimate rice grain yield and NUE in various rice production regions", "ja")

[MrS0m30n3]

Try running the following in the Python interpreter window and paste the output between triple backquotes (e.g. ```output```) here.

import logging
logging.basicConfig(level=logging.DEBUG)

import google_translate

# Make sure it says 0.2.2
print google_translate.__version__

translator  = google_translate.GoogleTranslator()
print translator.translate("field managements across China, was developed to estimate rice grain yield and NUE in various rice production regions", "ja")

[wotanzheng]

It still doesn't work. I am too happy to see Japanese chars. But the result is still None.

The output is

[MrS0m30n3]

You get None because Google detects a typo (has_typo = True).

You have two options here you can either correct all the typos in the text or use the get_info_dict method which returns the complete info dictionary and gives you more control.

Something like this should do the trick:

import google_translate

translator = google_translate.GoogleTranslator()

info_dict = translator.get_info_dict(<text here>, "ja")
print info_dict["translation"]

[MrS0m30n3]

@wotanzheng if the above solution works please close this issue.

[wotanzheng]

Thanks. it works on one sentence. I am just trying to txt batch translation. Sorry. I forgot to close it.

[MrS0m30n3]

Since the command line utility does not work for Windows you can copy the code from https://github.com/MrS0m30n3/google-translate/blob/master/bin/google-translate#L135 (until line 155) and make some changes to make it run. Also, you should change line-150 to use the get_info_dict method like this:

info_dict = translator.get_info_dict(utils.unquote_unicode(text), args.dst_lang, args.src_lang)
trans_content.append(info_dict["translation"])

[wotanzheng]

Thank you so much:-) I'll try it.

[MrS0m30n3]

Here is a quick script i wrote just now. You can adjust it to make it better

import re
import sys

from google_translate import GoogleTranslator, utils

encoding = "UTF-8"

NEWLINE_REPLACE = '\n\u2622\n'

NEWLINE_REPLACE_PATTERN = re.compile('\n?\u2622\n?', re.UNICODE)

def translate(filename, dst_lang):
    with open(filename) as input_file:
        translator = GoogleTranslator()

        content = [line.strip().decode(encoding) + NEWLINE_REPLACE for line in input_file]

        content = ''.join(content)

        quoted_punctuations = [utils.quote_unicode(char) for char in utils.PUNCTUATIONS]
        quoted_content = utils.quote_unicode(content)

        # Split the text into chunks of max size and translate each one
        trans_content = []
        for text in utils.split_text(quoted_content, GoogleTranslator.MAX_INPUT_SIZE, quoted_punctuations):
            info_dict = translator.get_info_dict(utils.unquote_unicode(text), dst_lang)

            trans_content.append(info_dict["translation"])

        trans_content = ' '.join(trans_content)

        # Replace the NEWLINE_REPLACE chars with the newline char
        results = NEWLINE_REPLACE_PATTERN.sub('\n', trans_content)

        print results

if __name__ == "__main__":
    if len(sys.argv) != 3:
        print "Usage: ./translate-file.py <file> <dst-lang>"
        exit(1)

    translate(sys.argv[1], sys.argv[2])

[wotanzheng]

Thank you so much. You are so nice. I will test the program tomorrow.:-P
