我正在制作這個應用程式，它將顯示串列中隨機朋友的名字（串列在代碼中）。但是當我運行應用程式時，tkinter 視窗中沒有顯示任何內容，除了標題
編碼：

順便說一句，我正在使用 anaconda spyder
uj5u.com熱心網友回復：
您需要將 GUI 代碼移到randomnumber函式之外，否則永遠不會創建小部件：
from tkinter import *
import random
root = Tk()
root.title("Luck Friend Wheel")
root.geometry("400x400")
list = ["James", "Isabella", "Sophia", "Olivia", "Peter"]
def randomnumber():
random_no = random.randint(0, 4)
random_lucky_friend = list[random_no]
print("Your lucky friend is: " random_lucky_friend)
btn = Button(root, text= "Who is your lucky friend?", command = randomnumber)
btn.place(relx=0.4,rely=0.5, anchor=CENTER)
root.mainloop()
