A flexible python tool to translate between different languages in a simple way.
Project description
deep_translator
Translation for humans
A flexible FREE and UNLIMITED tool to translate between different languages in a simple way using multiple translators.
Free software: MIT license
Documentation: https://deep-translator.readthedocs.io.
Motivation
I needed to translate a text using python. It was hard to find a simple way to do it. There are other libraries that can be used for this task, but most of them are buggy, not free, limited, not supported anymore or complex to use.
Therefore, I decided to build this simple tool. It is 100% free, unlimited, easy to use and provide support for all languages.
Basically, my goal was to integrate support for multiple famous translators in this tool.
When you should use it
If you want to translate text using python
If you want to translate from a file
If you want to get translations from many sources and not only one
If you want to automate translations
If you want to compare different translations
If you want to detect language automatically
Why you should use it
High level of abstraction
Automatic language detection
Easy to use and extend
It’s the only python tool that integrates many translators
Stable
Support for most famous universal translators
Features
Support for google translate
Support for Pons translator (pons.com)
Support for the Linguee translator
Support for the Mymemory translator
Automatic language detection
Translate directly from a text file
Get multiple translation for a word
Automate the translation of different paragraphs in different languages
Translate directly from terminal (version >= 1.1.0)
Installation
Install the stable release:
$ pip install -U deep_translator
take a look at the docs if you want to install from source.
Usage
from deep_translator import (GoogleTranslator,
PonsTranslator,
LingueeTranslator,
MyMemoryTranslator,
detect_language)
Example of checking the supported languages for the google translator:
# 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:
lang = detect_language('bonjour la vie', api_key='your_api_key')
print(lang) # output: fr
Simple translation:
text = 'happy coding'
translated = GoogleTranslator(source='auto', target='de').translate(text=text)
# Alternatively, you can pass languages by their name:
translated = GoogleTranslator(source='english', target='german').translate(text=text)
Translate from a file:
translated = GoogleTranslator(source='auto', target='german').translate_file('path/to/file')
Automate translation by detecting the source language
# or maybe you have many sentences in different languages and want to automate the translation process
translated = GoogleTranslator(source='auto', target='de').translate_sentences(your_list_of_sentences)
Maybe you would like to use the Pons translator: Pons.com
word = 'good'
translated_word = PonsTranslator(source='english', target='french').translate(word)
# 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)
Alternatively deep_translator (version >= 1.0.0) supports the Linguee translator:
word = 'good'
translated_word = LingueeTranslator(source='english', target='french').translate(word)
# 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)
The mymemory translator is also supported for version >= 1.0.2:
word = 'Keep it up. You are awesome'
translated_word = MyMemoryTranslator(source='auto', target='french').translate(word)
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"

The Translator++ mobile app
After developing the deep_translator, I realised how cool this would be if I can use it as an app on my mobile phone. Sure, there is google translate, pons and linguee apps etc.. but isn’t it cooler to make an app where all these translators are integrated?
Long story short, I started working on the app. I decided to use the kivy framework since I wanted to code in python and to develop a cross platform app. I open sourced the Translator++ app on my github too. Feel free to take a look at the code or make a pull request ;)
I published the first release on google play store on 02-08-2020
