Usage¶

In this section, demos on how to use all different integrated translators are provided.

Note

You can always pass the languages by the name or by abbreviation.

Example: If you want to use english as a source or target language, you can pass english or en as an argument

Imports¶

from deep_translator import (GoogleTranslator,
                             PonsTranslator,
                             LingueeTranslator,
                             MyMemoryTranslator,
                             YandexTranslator,
                             DeeplTranslator,
                             QcriTranslator,
                             single_detection,
                             batch_detection)

Check Supported Languages¶

Note

You can check the supported languages of each translator by calling the get_supported_languages function as a static method.

# default return type is a list
langs_list = GoogleTranslator().get_supported_languages()  # output: [arabic, french, english etc...]

# alternatively, you can the dictionary containing languages mapped to their abbreviation
langs_dict = GoogleTranslator().get_supported_languages(as_dict=True)  # output: {arabic: ar, french: fr, english:en etc...}

Language Detection¶

Note

You can also detect language automatically. Notice that this package is free and my goal is to keep it free. Therefore, you will need to get your own api_key if you want to use the language detection function. I figured out you can get one for free here: https://detectlanguage.com/documentation

Single Text Detection

lang = single_detection('bonjour la vie', api_key='your_api_key')
print(lang) # output: fr

Batch Detection

lang = batch_detection(['bonjour la vie', 'hello world'], api_key='your_api_key')
print(lang) # output: [fr, en]

Google Translate¶

text = 'happy coding'

You can use automatic language detection to detect the source language:

translated = GoogleTranslator(source='auto', target='de').translate(text=text)

You can pass languages by name or by abbreviation:

translated = GoogleTranslator(source='auto', target='german').translate(text=text)

# Alternatively, you can pass languages by their abbreviation:
translated = GoogleTranslator(source='en', target='de').translate(text=text)

Translate batch of texts

texts = ["hallo welt", "guten morgen"]

# the translate_sentences function is deprecated, use the translate_batch function instead
translated = GoogleTranslator('de', 'en').translate_batch(texts)

Translate from a file:

translated = GoogleTranslator(source='auto', target='german').translate_file('path/to/file')

Mymemory Translator¶

Note

As in google translate, you can use the automatic language detection with mymemory by using “auto” as an argument for the source language. However, this feature in the mymemory translator is not so powerful as in google translate.

Simple translation

text = 'Keep it up. You are awesome'

translated = MyMemoryTranslator(source='auto', target='french').translate(text)

Translate batch of texts

texts = ["hallo welt", "guten morgen"]

# the translate_sentences function is deprecated, use the translate_batch function instead
translated = MyMemoryTranslator('de', 'en').translate_batch(texts)

Translate from file

path = "your_file.txt"

translated = MyMemoryTranslator(source='en', target='fr').translate_file(path)

DeeplTranslator¶

Note

In order to use the DeeplTranslator translator, you need to generate an api key. Visit https://www.deepl.com/en/docs-api/ for more information

Simple translation

text = 'Keep it up. You are awesome'

translated = DeeplTranslator("your_api_key").translate(text)

Translate batch of texts

texts = ["hallo welt", "guten morgen"]

# the translate_sentences function is deprecated, use the translate_batch function instead
translated = DeeplTranslator("your_api_key").translate_batch(texts)

QcriTranslator¶

Note

In order to use the QcriTranslator translator, you need to generate a free api key. Visit https://mt.qcri.org/api/ for more information

Check languages

# as a property
print("language pairs: ", QcriTranslator("your_api_key").languages)

Check domains

# as a property
print("domains: ", QcriTranslator("your_api_key").domains)

Text translation

text = 'Education is great'

translated = QcriTranslator("your_api_key").translate(source='en', target='ar', domain="news", text=text)
# output -> التعليم هو عظيم

# see docs for batch translation and more.

Linguee Translator¶

word = 'good'

Simple Translation

translated_word = LingueeTranslator(source='english', target='french').translate(word)

# pass language by their abbreviation
translated_word = LingueeTranslator(source='en', target='fr').translate(word)

Return all synonyms or words that match

# set the argument return_all to True if you want to get all synonyms of the word to translate
translated_word = LingueeTranslator(source='english', target='french').translate(word, return_all=True)

Translate a batch of words

translated_words = LingueeTranslator(source='english', target='french').translate_words(["good", "awesome"])

PONS Translator¶

Note

You can pass the languages by the name or by abbreviation just like previous examples using GoogleTranslate

word = 'awesome'

Simple Translation

translated_word = PonsTranslator(source='english', target='french').translate(word)

# pass language by their abbreviation
translated_word = PonsTranslator(source='en', target='fr').translate(word)

Return all synonyms or words that match

# set the argument return_all to True if you want to get all synonyms of the word to translate
translated_word = PonsTranslator(source='english', target='french').translate(word, return_all=True)

Translate a batch of words

translated_words = PonsTranslator(source='english', target='french').translate_words(["good", "awesome"])

Yandex Translator¶

Note

You need to require n private api key if you want to use the yandex translator. Visit the official website for more information about how to get one

Language detection

lang = YandexTranslator('your_api_key').detect('Hallo, Welt')
print(f"language detected: {lang}")  # output -> language detected: 'de'

Text translation

# with auto detection | meaning provide only the target language and let yandex detect the source
translated = YandexTranslator('your_api_key').translate(source="auto", target="en", text='Hallo, Welt')
print(f"translated text: {translated}")  # output -> translated text: Hello world

# provide source and target language explicitly
translated = YandexTranslator('your_api_key').translate(source="de", target="en", text='Hallo, Welt')
print(f"translated text: {translated}")  # output -> translated text: Hello world

File translation

translated = YandexTranslator('your_api_key').translate_file(source="auto", target="en", path="path_to_your_file")

Batch translation

translated = YandexTranslator('your_api_key').translate_batch(source="auto", target="de", batch=["hello world", "happy coding"])

Libre Translator¶

Note

Libre translate has multiple mirrors which can be used for the API endpoint. Some require an API key to be used. By default the base url is set to libretranslate.de . This can be set using the “base_url” input parameter.

text = 'laufen'
translated = LibreTranslator(source='auto', target='en', base_url = 'https://libretranslate.com/', api_key = 'your_api_key').translate(text=text)  # output: run

You can pass languages by name or by abbreviation:

translated = LibreTranslator(source='german', target='english').translate(text=text)

# Alternatively, you can pass languages by their abbreviation:
translated = LibreTranslator(source='de', target='en').translate(text=text)

Translate batch of texts

texts = ["hallo welt", "guten morgen"]
translated = LibreTranslator(source='auto', target='en').translate_batch(texts)

Translate from a file:

translated = LibreTranslator(source='auto', target='en').translate_file('path/to/file')

Usage from Terminal¶

For a quick access, you can use the deep_translator from terminal. For this to work, you need to provide the right arguments, which are the translator you want to use, source language, target language and the text you want to translate.

For example, provide “google” as an argument to use the google translator. Alternatively, you can use the other supported translators. Just read the documentation to have an overview about the supported translators in this library.

$ deep_translator --translator "google" --source "english" --target "german" --text "happy coding"

Or you can go for the short version:

$ deep_translator -trans "google" -src "english" -tg "german" -txt "happy coding"

If you want, you can also pass the source and target language by their abbreviation

$ deep_translator -trans "google" -src "en" -tg "de" -txt "happy coding"
