3 calling methods of Google multilingual translation interface (Python)

2022.10.01 update:

Since Google Translate has stopped serving in China, please move to the Youdao translation interface: Youdao translation multilingual interface calling method (Python) In our daily life and work, we often need to use translation tools. Since Google Translate has stopped serving in China, Youdao Translate has been used as a substitute, and now there are two ways to call Youdao Translate interface through Python. https://blog.csdn.net/qq_40039731/article/details/127302928

        At the end of September, Google Translate, a webpage translation tool owned by the search giant Google, stopped its service in China. Now, when you visit the translate.google.cn webpage, it will point to the Google Hong Kong station. As early as 2010, after Google announced its withdrawal from China, only two services, Google Translate and Google Maps, were retained. From February 3, 2020, Google Maps will stop serving in China, and now, the last Google translation service is also closed.
        It is understood that many users have reported on the Reddit website that Google Translate cannot be used normally in China. Later, a Google spokesperson replied to the foreign media TechCrunch by email, acknowledging that Google Translate service was stopped in China, and stated that the reason was "usage rate too low".

original:

        Google Translate is a free translation service that supports instant translation between up to 133 languages. In addition, Google Translate uses Statistical Machine Translation (SMT), which will conduct a large number of searches and speculations in human-translated documents during the translation process, and use this to obtain the most suitable translation results.

        In our daily life and work, we often need to use translation tools. Among many translation tools, I personally prefer Google Translate, so here are three ways to call the Google Translate interface through Python.

 method one

import requests
def translate_1(text, src_lang='auto', to_lang='en'):
    googleapis_url = 'https://translate.googleapis.com/translate_a/single'
    url = '%s?client=gtx&sl=%s&tl=%s&dt=t&q=%s' % (googleapis_url,src_lang,to_lang,text)
    data = requests.get(url).json()
    res = ''.join([s[0] for s in data[0]])
    return res

Method Two

# pip install bs4
import requests
from bs4 import BeautifulSoup
def translate_2(text, src_lang='auto', to_lang='en'):
    url = 'https://translate.google.cn/m?q=%s&tl=%s&sl=%s' % (text,to_lang,src_lang)
    soup = BeautifulSoup(requests.get(url).text,'lxml')
    res = soup.find('div',{'class':'result-container'}).text
    return res

method three

# pip install googletrans==4.0.0-rc1
from googletrans import Translator
def translate_3(text, src_lang='auto', to_lang='en'):
    translator = Translator(service_urls=['translate.google.cn'])
    res = translator.translate(text, dest=to_lang, src=src_lang).text
    return res

 Get all languages ​​and their corresponding encodings

import requests
from bs4 import BeautifulSoup
def get_all_langcode():
    response = requests.get(url='https://translate.google.cn')
    soup = BeautifulSoup(response.text,'lxml')
    res_dict = {}
    for res in soup.find_all('div',{'class':'qSb8Pe'}):
        res_dict[res['data-language-code']] = res.find('div',{'class':'Llmcnf'}).text
    return res_dict
