python怎么打开文件窗口

import tkinter as tkdef open_file_window():    # 创建一个Tkinter窗口    root = tk.Tk()    root.title("文件选择")    # 创建一个文件选择器小部件    file_path = tk.filedialog.askopenfilename()    if file_path:        # 打开文件并读取其内容        with open(file_path, 'r') as f:            file_content = f.read()        # 将文件内容显示在窗口中        text_area = tk.Text(root, height=10, width=50)        text_area.insert(tk.END, file_content)        text_area.pack()    # 启动Tkinter事件循环    root.mainloop()
