如何将我的python逻辑应用到tkinter GUI中？这是一个简单的GET请求程序

import tkinter as tk
import requests

root = tk.Tk()
root.title("GET请求程序")

label = tk.Label(root, text="请输入URL:")
label.pack()

entry = tk.Entry(root)
entry.pack()

button = tk.Button(root, text="发送请求", command=send_request)
button.pack()

result_label = tk.Label(root, text="")
result_label.pack()

def send_request():
    url = entry.get()
    response = requests.get(url)
    result_label.config(text=response.text)

root.mainloop()
