Python简单爬虫有道翻译，有GUI窗口，用到request库和tkinter

from tkinter import *
import requests
root=Tk()
Label(root,text="待翻译").grid(row=0,column=0)
Label(root,text="已翻译").grid(row=1,column=0)
v1=StringVar()
v2=StringVar()
e1=Entry(root,textvariable=v1,background='red')
e2=Entry(root,textvariable=v2)
e1.grid(row=0,column=1,padx=10,pady=5)
e2.grid(row=1,column=1,padx=10,pady=5)
def show():
    content = e1.get()
    url = 'http://fanyi.youdao.com/translate?smartresult=dict&smartresult=rule'
    kv = {
        'User-Agent': 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/55.0.2883.87 Safari/537.36'
    }
    data = {'from': 'AUTO', 'to': 'AUTO', 'smartresult': 'dict', 'client': 'fanyideskweb', 'salt': '15720936967797',
            'sign': '632f606ac7bfb3eb82c6d16642f1780e',
            'ts': '1572093696779', 'bv': 'f4d62a2579ebb44874d7ef93ba47e822', 'doctype': 'json', 'version': '2.1',
            'keyfrom': 'fanyi.web', 'action': 'FY_BY_CLICKBUTTION'}
    data['i'] = content
    r = requests.get(url, data, headers=kv, timeout=30).json()
    print("翻译结果为：")
    print(r['translateResult'][0][0]['tgt'])
    e2.delete(0,END)#删除e2中原有的内容
    e2.insert(0,r['translateResult'][0][0]['tgt'])

Button(root,text="翻译",width=10,command=show)\
    .grid(row=3,column=0,sticky=W,padx=10,pady=5)
Button(root,text="退出",width=10,command=root.quit)\
    .grid(row=3,column=1,sticky=W,padx=10,pady=5)

mainloop()
