python实现在线翻译功能
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 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;
a = b.charAt(c) == Yb ? a + d & 4294967295 : a ^ d

return a
