Googletrans

Googletrans is a free and unlimited python library that implemented Google Translate API. This uses the Google Translate Ajax API <https://translate.google.com>__ to make calls to such methods as detect and translate.

Compatible with Python 3.6+.

For details refer to the API Documentation <https://py-googletrans.readthedocs.io/en/latest>__.

Features

Fast and reliable - it uses the same servers that translate.google.com uses
Auto language detection
Bulk translations
Customizable service URL
HTTP/2 support

TODO


more features are coming soon.

-  Proxy support
-  Internal session management (for better bulk translations)

HTTP/2 support

This library uses httpx for HTTP requests so HTTP/2 is supported by default.

You can check if http2 is enabled and working by the ._response.http_version of Translated or Detected object:

.. code:: python

translator.translate('테스트')._response.http_version

'HTTP/2'

How does this library work


You may wonder why this library works properly, whereas other
approaches such like goslate won't work since Google has updated its
translation service recently with a ticket mechanism to prevent a lot of
crawler programs.

I eventually figure out a way to generate a ticket by reverse
engineering on the `obfuscated and minified code used by Google to
generate such
token <https://translate.google.com/translate/releases/twsfe_w_20170306_RC00/r/js/desktop_module_main.js>`__,
and implemented on the top of Python. However, this could be blocked at
any time.

--------------

Installation
------------

To install, either use things like pip with the package "googletrans"
or download the package and put the "googletrans" directory into your
python path.

.. code:: bash

    $ pip install googletrans

Basic Usage
-----------

If source language is not given, google translate attempts to detect the
source language.

.. code:: python

    >>> from googletrans import Translator
    >>> translator = Translator()
    >>> translator.translate('안녕하세요.')
    # <Translated src=ko dest=en text=Good evening. pronunciation=Good evening.>
    >>> translator.translate('안녕하세요.', dest='ja')
    # <Translated src=ko dest=ja text=こんにちは。 pronunciation=Kon'nichiwa.>
    >>> translator.translate('veritas lux mea', src='la')
    # <Translated src=la dest=en text=The truth is my light pronunciation=The truth is my light>

Customize service URL

You can use another google translate domain for translation. If multiple URLs are provided, it then randomly chooses a domain.

.. code:: python

>>> from googletrans import Translator
>>> translator = Translator(service_urls=[
      'translate.google.com',
      'translate.google.co.kr',
    ])

Advanced Usage (Bulk)


Array can be used to translate a batch of strings in a single method
call and a single HTTP session. The exact same method shown above works
for arrays as well.

.. code:: python

    >>> translations = translator.translate(['The quick brown fox', 'jumps over', 'the lazy dog'], dest='ko')
    >>> for translation in translations:
    ...    print(translation.origin, ' -> ', translation.text)
    # The quick brown fox  ->  빠른 갈색 여우
    # jumps over  ->  이상 점프
    # the lazy dog  ->  게으른 개

Language detection

The detect method, as its name implies, identifies the language used in a given sentence.

.. code:: python

>>> from googletrans import Translator
>>> translator = Translator()
>>> translator.detect('이 문장은 한글로 쓰여졌습니다.')
# <Detected lang=ko confidence=0.27041003>
>>> translator.detect('この文章は日本語で書かれました。')
# <Detected lang=ja confidence=0.64889508>
>>> translator.detect('This sentence is written in English.')
# <Detected lang=en confidence=0.22348526>
>>> translator.detect('Tiu frazo estas skribita en Esperanto.')
# <Detected lang=eo confidence=0.10538048>

GoogleTrans as a command line application

.. code:: bash

$ translate -h
usage: translate [-h] [-d DEST] [-s SRC] [-c] text

Python Google Translator as a command-line tool

positional arguments:
  text                  The text you want to translate.

optional arguments:
  -h, --help            show this help message and exit
  -d DEST, --dest DEST  The destination language you want to translate.
                        (Default: en)
  -s SRC, --src SRC     The source language you want to translate. (Default:
                        auto)
  -c, --detect

$ translate "veritas lux mea" -s la -d en
[veritas] veritas lux mea
    ->
[en] The truth is my light
[pron.] The truth is my light

$ translate -c "안녕하세요."
[ko, 1] 안녕하세요.

Running Tests

$ pipenv run python -m unittest discover

Note on library usage

DISCLAIMER: this is an unofficial library using the web API of translate.google.com and also is not associated with Google.

The maximum character limit on a single text is 15k.
Due to limitations of the web version of google translate, this API does not guarantee that the library would work properly at all times (so please use this library if you don't care about stability).
Important: If you want to use a stable API, I highly recommend you to use Google's official translate API <https://cloud.google.com/translate/docs>__.
If you get HTTP 5xx error or errors like #6, it's probably because Google has banned your client IP address.
