如何根据条目小部件更新字典值: Tkinter

import tkinter as tk

window = tk.Tk()

my_dict = {'key1': 'value1', 'key2': 'value2', 'key3': 'value3'}

key_entry = tk.Entry(window)
key_entry.pack()

def update_dict_value():
    key = key_entry.get()
    if key in my_dict:
        # 获取要更新的值
        value = value_entry.get()
        # 更新字典值
        my_dict[key] = value
        # 清空输入框
        key_entry.delete(0, tk.END)
        value_entry.delete(0, tk.END)
        # 打印更新后的字典
        print(my_dict)
    else:
        print("Key not found in dictionary!")

update_button = tk.Button(window, text="Update", command=update_dict_value)
update_button.pack()

value_entry = tk.Entry(window)
value_entry.pack()

window.mainloop()
