对于需要大量翻译的数据，人工翻译太慢，此时需要使用软件进行批量翻译。

1.使用360的翻译

def fanyi_word_cn(string):
 url="https://fanyi.so.com/index/search"
 #db_path = './db/tasks.db'
 Form_Data= {}

 #这里输入要翻译的英文
 Form_Data['query']= string
 Form_Data['eng']= '1'

 #用urlencode把字典变成字符串，#服务器不接受字典，只接受字符串和二进制
 data= parse.urlencode(Form_Data).encode('utf-8')

 #改成服务器可识别的数据后，请求，获取回应数据
 response= request.urlopen(url, data)

 html= response.read().decode("utf-8")#解码方式

 #java中的对象（集合）和数组（元素为集合）,loads可转Python字典
 result= json.loads(html)

 #字典调取键名data下的键名fanyi,获取其值
 translate_result= result["data"]["fanyi"]
 #print(translate_result)
 return translate_result

2.使用Google自带的API来翻译

注意，需要安装API模块即可。

pip install translator

#google api, per 1000 words everyday
def translate_cn_api(content):
 translator= Translator(to_lang="zh")
 translation = translator.translate(content)
 return translation

3.使用Google翻译来做，是由于Google提供的API有字节限制，每天只能翻译1000字。

备注：环境准备

3.1 java环境

3.2 安装execjs模块

pip install PyExecJS

3.3 两个实现模块

HandleJs.py

#coding=utf-8
import execjs

class Py4Js(): 

 def __init__(self): 
 self.ctx = execjs.compile("""

 var k = "";

 var jd = ".";

 var Zb = "+-3^+b+-f"; 

 for (var e = [], f = 0, g = 0; g < a.length; g++) { 
  var m = a.charCodeAt(g);

 } 
 a = b; 
 for (f = 0; f < e.length; f++) a += e[f], 
 a = RL(a, $b); 
 a = RL(a, Zb); 
 a ^= b1 || 0; 
 0 > a && (a = (a & 2147483647) + 2147483648); 
 a %= 1E6; 
 return a.toString() + jd + (a ^ b) 
 }; 

 function RL(a, b) { 
 var t = "a"; 
 var Yb = "+"; 
 for (var c = 0; c < b.length - 2; c += 3) { 
  var d = b.charAt(c + 2), 
  d = d >= t ? d.charCodeAt(0) - 87 : Number(d), 
  d = b.charAt(c + 1) == Yb ? a >>> d: a << d;

此处实现了德语翻译成中文和英文翻译成中文。
