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.

|
Features
|
||
|
|
--------
|
||
|
|
|
||
|
|
- Fast and reliable - it uses the same servers that
|
||
|
|
translate.google.com uses
|
||
|
|
- Auto language detection
|
||
|
|
- Bulk translations
|
||
|
|
- Customizable service URL
|
||
|
|
- Connection pooling (the advantage of using requests.Session)
|
||
|
|
- HTTP/2 support
|
||
|
|
|
||

|
||
|
|
Note on library usage
|
||
|
|
~~~~~~~~~~~~~~~~~~~~~
|
||
|
|
|
||
|
|
- 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.)
|
||
|
|
|
||
|
|
- 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.
|
||
|
|
|
||
|
|
----------
|
||
|
|
Quickstart
|
||
|
|
----------
|
||
|
|
|
||
|
|
You can install it from PyPI_:
|
||
|
|
|
||
|
|
.. sourcecode:: bash
|
||
|
|
|
||
|
|
$ pip install googletrans
|
||
|
|
|
||
|
|
.. _PyPI: https://pypi.python.org/pypi/googletrans
|
||
|
|
|
||
|
|
~~~~~~~~~~~~~~
|
||
|
|
HTTP/2 support
|
||
|
|
~~~~~~~~~~~~~~
|
||
|
|
|
||
|
|
This is a great deal for everyone! (up to 2x times faster in my test) If
|
||
|
|
you want to get googletrans faster you should install
|
||
|
|
`hyper <https://github.com/Lukasa/hyper>`__ package. Googletrans will
|
||
|
|
automatically detect if hyper is installed and if so, it will be used
|
||
|
|
for http networking.
|
||
|
|
|
||
|
|
~~~~~~~~~~~
|
||
|
|
Basic Usage
|
||
|
|
~~~~~~~~~~~
|
||
|
|
|
||
|
|
If source language is not given, google translate attempts to detect the
|
||
|
|
source language.
|
||
|
|
|
||
|
|
.. code-block:: 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 work
|
||
|
|
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
|
||
|
|
|
||
|
|
>>> 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>
