如何在Tkinter中仅验证非整数值的条目

import tkinter as tk
from tkinter import messagebox

window = tk.Tk()
entry = tk.Entry(window)
entry.pack()

def validate_input():
    value = entry.get()
    if value.isdigit():
        messagebox.showerror("错误", "请输入非整数值")
        return False
    return True

validate_cmd = window.register(validate_input)
entry.config(validate="key", validatecommand=(validate_cmd, "%P"))

window.mainloop()

import tkinter as tk

    if value.isdigit():

        return False
