这篇文章主要介绍如何使用python实现一款属于自己的翻译词典软件，文中介绍的非常详细，具有一定的参考价值，感兴趣的小伙伴们一定要看完！
1.先写一个登录的py文件，用python的tkinter库
2.再写一个py文件用于爬取有道翻译输出栏的内容
3.再利用python的tkinter库，完成软件运行的窗口
4.将窗口的返回值与爬取有道翻译的结果接口对一下
5.第二个py文件里import第一个py文件，两个文件相关联
请求方式为post，要注意from data里的值，这里可以在网页上再输一个想要翻译的内容，观察from data里的值的变化，可以确定&＃39;salt&＃39;、 ‘sign&＃39;、 &＃39;lts&＃39;这三个值变化
进入网页源代码搜索.js，找到对应的js文件，找到他们的加密规则，最后将获得的response转化为字典，提取结果
class YouDao(object):
a.LoginPage()
def __init__(self):
pass
def crawl(self, content):

先看一下软件效果，先登录
各种语言都可以转换
