tkinter :如何使用标签和条目在画布中显示任意大小的字典，并从输入操作字典

import tkinter as tk

window = tk.Tk()
window.title("显示字典")

canvas = tk.Canvas(window, width=400, height=300)
canvas.pack()

dictionary = {"key1": "value1", "key2": "value2", "key3": "value3"}
for i, key in enumerate(dictionary.keys()):
    label = tk.Label(canvas, text=key)
    label.place(x=10, y=i*30)

entry = tk.Entry(canvas)
entry.place(x=100, y=i*30)

def update_value():
    key = list(dictionary.keys())[i]
    value = entry.get()
    dictionary[key] = value

button = tk.Button(canvas, text="更新值", command=update_value)
button.place(x=200, y=i*30)

window.mainloop()
