tkinter做gui界面，测试时间为0，需要得到真实测试时间

利用tkinter做gui界面，测试时间为0，逻辑看着是跟我正常代码一样的，但还是没算出来，求解答

import tkinter as tk

count = 1

a = random.randint(1, 9)

mul01.set(str(a))

mul02 = tk.StringVar()

mul02.set(str(b))

count_title = tk.StringVar()

count_title.set('第1道题')

score_lab = tk.StringVar()

score_lab.set('0')

answer_lab = tk.StringVar()

gameove = tk.StringVar()

t=tk.StringVar()

window.mainloop()

用time.clock函数试试吧
