實現轉盤抽獎需要再開一個執行緒，要用到threading庫，執行程式如下圖所示

一個執行緒用來迴圈顯示面板，一個迴圈用來實現轉盤的迴圈

具體程式碼如下（程式碼在linux系統下pycharm中書寫）

import tkinter
# 匯入執行緒模組
import threading
import time

root = tkinter.Tk()
root.title('轉盤抽獎')
root.minsize(290,370)


# 擺放按鈕
btn1 = tkinter.Button(root, text = '藍芽耳機', bg = 'red')
btn1.place(x = 20, y = 20
 
, width = 70, height = 70)

btn2 = tkinter.Button(root, text = '再來一次', bg = 'white')
btn2.place(x = 110, y = 20, width = 70, height = 70)

btn3 = tkinter.Button(root, text = '抱枕', bg = 'white')
btn3.place(x = 200, y = 20, width = 70, height = 70)

btn4 = tkinter.Button(root, text = '謝謝惠顧', bg = 'white')
btn4.place(x = 20
 
, y = 110, width = 70, height = 70)

btn5 = tkinter.Button(root, text = '保溫杯', bg = 'white')
btn5.place(x = 200, y = 110, width = 70, height = 70)

btn6 = tkinter.Button(root, text = '充電寶', bg = 'white')
btn6.place(x = 20, y = 200, width = 70, height = 70)

btn7 = tkinter.Button(root, text = 'iphoneX', bg = 'white'
 
)
btn7.place(x = 110, y = 200, width = 70, height = 70)

btn8 = tkinter.Button(root, text = '謝謝惠顧', bg = 'white')
btn8.place(x = 200, y = 200, width = 70, height = 70)

# 將所有選項組成列表
prizelists = [btn1,btn2,btn3,btn5,btn8,btn7,btn6,btn4]

# 是否開啟迴圈的標誌
isloop = False
# 是否執行的標誌
functions = False

def round():
    # 判斷是否開始迴圈（防止多次按下開始按鈕程式開啟多次轉盤迴圈）
    if isloop == True:
        return

    # 初始化計數變數
    i = 0
    while True:
        # 延時操作
        time.sleep(0.06)
        # 將所有元件的背景顏色變為白色
        for j in prizelists:
            j['bg'] = 'white'
        # 將當前數值對應的元件變色
        prizelists[i]['bg'] = 'red'

        i += 1
        # 如果i大於最大索引直接歸零
        if i >= len(prizelists):
            i = 0
        if functions == True:
            continue
        else:
            break

# 建立一個新執行緒的函式
def newtask():
    global isloop
    global functions
    # 建立執行緒
    t = threading.Thread(target = round)
    # 開啟執行緒執行
    t.start()
    # 設定迴圈開始標誌
    isloop = True
    # 是否執行的標誌
    functions = True

# 定義停止迴圈的函式
def stop():
    global isloop
    global functions

    functions = False
    isloop = False

# 開始按鈕
btn_start = tkinter.Button(root, text = '開始', command = newtask)
btn_start.place(x = 80, y = 300, width = 50, height = 50)

# 結束按鈕

btn_stop = tkinter.Button(root, text = '結束', command = stop)
btn_stop.place(x = 150, y = 300, width = 50, height = 50)

root.mainloop()
