为什么我的按钮不显示？？

Question

#Last one Looses (II)
from tkinter import *
from tkinter import ttk
root = Tk()

#window
root.title("Last one Looses Mark II")

#Counters Entry
counters = StringVar()
countersL = Label(root, text = "How many counters do you want to play with (10-50)")
countersL.pack(side = LEFT)
countersE = Entry(root, textvariable = counters, bd = 5)
countersE.pack(side = RIGHT)
#Function to process this
def countersinput():
    no_counters = int(input(counters.get()))
no_counters = int(input(counters.get()))
#Submit Button
countersB = Button(root, text = "Submit", command = countersinput)
countersB.pack(side = BOTTOM)
#Making sure the counters are between 10-50
while no_counters > 50 or no_counters < 10:
    Error = Message(root, text="You need to pick between 10 and 50 counters...")
    Error.pack()
    counters = StringVar()
    countersL = Label(root, text = "How many counters do you want to play with (10-50)")
    countersL.pack(side = LEFT)
    countersE = Entry(root, textvariable = counters, bd = 5)
    countersE.pack(side = RIGHT)
    def countersinput():
        no_counters = int(input(counters.get()))
    countersB = Button(root, text = "Submit", command = countersinput)
    countersB.pack(side = BOTTOM)

#Sucess Message
Sucess = Message(root, text=("You are playing with",no_counters,"counters"))

root.mainloop()

每当我在 IDLE 中运行它时，tkinter 窗口都不会出现，当我将它运行到命令行（python one...）时，它会显示窗口但没有“提交”按钮。

我真的很困惑，请帮忙！

首先，您是否意识到您的 GUI 程序要求从命令行输入，并且您在创建提交按钮之前 这样做了？这就是提交按钮未显示的原因。如果您正在编写 GUI 程序，则不应尝试从命令行读取输入。

如果您从终端输入 10 到 50 之间的数字，您的代码应该会显示一个窗口。但是，如果您输入超出该范围的数字，则由于while no_counters ... 循环，将不会显示任何内容。该循环将无限运行，阻止与 GUI 的任何其他交互，并阻止任何其他小部件出现。
