请教面向对象的编程思路

彩虹七号

对面向对象编程不是太理解
下面的例子怎样改成面向对象编程，求思路
import tkinter as tk
import requests
import json

root = tk.Tk()

def operation():
    content = e1.get()
    if content == '':
        pass
    else:
        e2.delete(0, tk.END)
        v2.set(translation(content))

def translation(content):
    url = "http://fanyi.youdao.com/translate?smartresult=dict&smartresult=rule"
    data = {}
    data['i'] = content
    data['from'] = 'AUTO'
    data['to'] = 'AUTO'
    data['smartresult'] = 'dict'
    data['client'] = 'fanyideskweb'
    data['salt'] = '1542686477843'
    data['sign'] = 'ff690fdd9bcfe53ac87a76bd7690cea3'
    data['doctype'] = 'json'
    data['version'] = '2.1'
    data['keyfrom'] = 'fanyi.web'
    data['action'] = 'FY_BY_REALTIME'
    data['typoResult'] = 'false'

    response = requests.post(url,data=data)
    html = json.loads(response.text)
    return html['translateResult'][0][0]['tgt']

frame = tk.LabelFrame(root, text='这是一个小小的翻译程序')
frame.pack(padx=5, pady=5, expand=1)

label1 = tk.Label(frame, text='输入要翻译的内容：')
label2 = tk.Label(frame, text='结果：')
label1.grid(row=0, column=0)
label2.grid(row=1, column=0)

v1 = tk.StringVar()
v2 = tk.StringVar()

e1 = tk.Entry(frame, textvariable=v1, width=30)
e2 = tk.Entry(frame, textvariable=v2, width=30, state='readonly')
e1.grid(row=0, column=1, padx=10, pady=5)
e2.grid(row=1, column=1, padx=10, pady=5)

button1 = tk.Button(frame, text='翻译', command=operation, width=10)
button2 = tk.Button(frame, text='退出', command=root.quit, width=10)
button1.grid(sticky=tk.W, row=2, column=0, padx=10, pady=5)
button2.grid(sticky=tk.E, row=2, column=1, padx=10, pady=5)

root.mainloop()

塔利班

面向对象无非是定义类，函数什么的，你是想把哪个通用化
