Tkinter 不打开窗口

Question

我正在创建一个允许用户制作自定义骰子的程序，但是当我打开一个带有调用后端骰子掷骰逻辑的按钮的 GUI 窗口时，它会中断。换句话说，窗口没有打开，代码只是在终端中运行。当按钮像我想要的那样被单击时不会发生这种情况，而是当我运行代码时，它不会打开任何 GUI 窗口并且代码在终端中执行。代码在没有 GUI 的情况下工作，如果我取出骰子按钮回调，GUI 可以工作，但不能一起工作。

感谢任何帮助！

import tkinter as tk


def dice_roll():
      dice = []
      x = 0

# used to check if the input is a whole number, if it isn't, you get a message
while True:
    while x == 0:
        try:
            SIDE_AMT = int(input("How many sides would you like? (min is 2, max is infinite): "))    # amt is amount
            x = 1
        except ValueError:
            print("Sorry it has to be a whole number.")

    if SIDE_AMT > 1:
        for side in range(SIDE_AMT):
            print(f"What would you like side {side + 1} to be?:")
            dice.append(str(input()))
        break
    else:
        print("You can't have a dice with one side!")
        x = 0

# roll function

    dice_side = random.choice(dice)
    print(f"I choose {dice_side}!")

            roll()
        else:

        roll_num += 1

    elif roll_num == 1:

你可能想做这样的事情：

import tkinter as tk
from random import choice


root = tk.Tk()
root.geometry('400x600')
root.resizable(False, False)
root.config(bg='light blue')

dice_numbers = [1, 2, 3, 4, 5, 6]
rolled_nums = []


def roll():
    if len(rolled_nums):
        rolled_nums[0].pack_forget()
        rolled_nums.pop(0)
    chosen_number = choice(dice_numbers)
    text = tk.Label(root, text=f'{chosen_number}',
                                font='arial 500 bold', bg='light blue')
    text.pack()
    rolled_nums.append(text)


button = tk.Button(root, text='Roll Dice!', font='arial 20 bold', relief='raised', width='300',
                   bg='dark red', fg='black', command=lambda: roll())
button.pack()

root.mainloop()
