Question

所以我在制作更换模具时遇到了麻烦

出于某种原因，我的功能（dice_roller）在我按下按钮之前运行，这对我没有意义。

只有在被告知的情况下才执行功能吗？

import tkinter,random
from tkinter import messagebox
window=tkinter.Tk()
window.title("Aidan's Dice Roller")
canvas = tkinter.Canvas(window, width=900, height=900)
canvas.pack()
canvas.create_rectangle(0,0,900,900, fill='black')
messagebox.showwarning("Dice Roller", "Do you want to proceed?")
dice1 = tkinter.PhotoImage(file="C:\\Users\\2019200\\Desktop\\Dice\\dice1.gif")
dice2 = tkinter.PhotoImage(file="C:\\Users\\2019200\\Desktop\\Dice\\dice2.gif")
dice3 = tkinter.PhotoImage(file="C:\\Users\\2019200\\Desktop\\Dice\\dice3.gif")
dice4 = tkinter.PhotoImage(file="C:\\Users\\2019200\\Desktop\\Dice\\dice4.gif")
dice5 = tkinter.PhotoImage(file="C:\\Users\\2019200\\Desktop\\Dice\\dice5.gif")
dice6 = tkinter.PhotoImage(file="C:\\Users\\2019200\\Desktop\\Dice\\dice6.gif")
dice1 = tkinter.PhotoImage(file="C:\\Users\\2019200\\Desktop\\Dice\\dice1.gif")
canvas.create_image(450, 350, image=dice1)
while True:
    x=random.randint(1,6)
    print(x)
def dice_roller():
    global x
    if x==1:
        canvas.create_image(450, 350, image=dice1)
    elif x==2:
        canvas.create_image(450, 350, image=dice2)
    elif x==3:
        canvas.create_image(450, 350, image=dice3)
    elif x==4:
        canvas.create_image(450, 350, image=dice4)
    elif x==5:
        canvas.create_image(450, 350, image=dice5)
    elif x==6:
        canvas.create_image(450, 350, image=dice6)
    window.update()
dice_button = tkinter.Button(window, text="hit button for die roll",height=10, width=80, command=dice_roller())
dice_button.place(x=160, y=600)
window.mainloop()

问题来自这条线：

dice_button = tkinter.Button(window, text="hit button for die roll",height=10, width=80, command=dice_roller())

您正在调用dice_roller()函数，而不是将其分配给tkinter.Button

这里是固定线路：

dice_button = tkinter.Button(window, text="hit button for die roll",height=10, width=80, command=dice_roller) #Notice the removed brackets

希望有所帮助

我的功能运行，无需通过tkinter按钮告诉
