python+tkinter下载

以下是一个使用Python和tkinter库进行文件下载的简单示例：

import tkinter as tk
from tkinter import filedialog
import urllib.request

def download_file():
    url = entry.get()
    save_path = filedialog.asksaveasfilename(defaultextension=".txt")
    urllib.request.urlretrieve(url, save_path)
    label.config(text="文件下载完成！")

# 创建窗口
window = tk.Tk()
window.title("文件下载")
window.geometry("300x150")

# 创建标签和输入框
label = tk.Label(window, text="请输入文件的URL地址：")
label.pack()
entry = tk.Entry(window)
entry.pack()

# 创建下载按钮
button = tk.Button(window, text="下载文件", command=download_file)
button.pack()

# 运行窗口
window.mainloop()
