数学游戏 Tkinter 中的 Python 计时器

Question

我想为我的简单数学游戏添加一个计时器。到目前为止，一切正常，用户在按下按钮时会收到问题，并会收到有关答案的反馈。我想为用户添加一个计时器，以查看回答乘法需要多长时间。这是我这个数学游戏原型(prototype)的最后一部分。我希望计时器在用户单击“nytt tal”时启动，这意味着瑞典语中的新数字，并在用户单击“svar”时停止计时器，这意味着在瑞典语中回答。这是我的代码。

from Tkinter import *import tkMessageBoximport randomimport timeimport sys# Definition for the question asked to user def fraga1():    global num3     num3 = random.randint(1, 10)    global num4     num4 = random.randint(1, 10)    global svar1     svar1 = num3 * num4    label1.config(text='Vad blir ' + str(num3) + '*' + str(num4) + '?')    entry1.focus_set()#The answer giving feedback based on answerdef svar1():   mainAnswer = entry1.get()   if len(mainAnswer) == 0:      tkMessageBox.showwarning(message='Skriv in några nummer!')   return   if int(mainAnswer) != svar1:      tkMessageBox.showwarning(message='Tyvärr det rätta svaret: ' + str(svar1))   else:      tkMessageBox.showinfo(message='RÄTT!! :)')#The quit button definitiondef quit():   global root   root.destroy()#Definition for the timer this part doesnt workdef start():   global count_flag    fraga1()   count_flag = True   count = 0.0   while True:      if count_flag == False:          break   label['text'] = str(count)   time.sleep(0.1)   root.update()   count += 0.1#Window coderoot = Tk()root.title("multiplikations tidtagning")root.geometry('800x500')count_flag = True# Welcome message in labelslabel2 = Label(root, text="Hej!\n  Nu ska vi lösa lite matteproblem!")label2.config(font=('times', 18, 'bold'), fg='black', bg='white')label2.grid(row=0, column=0)#Instructions how to play in labelslabel3 = Label(root, text="Instruktioner!\n  För att starta ett spel tryck på nyttspel") label3.config(font=('times', 12, 'bold'), fg='black', bg='white')label3.grid(row=2, column=2)#other labellabel1 = Label(root)label1.grid(row=2, column=0)# entry widget for the start buttonentry1 = Entry(root)entry1.grid(row=3, column=0)# restart gives a new questionentry1.bind('', func=lambda e:checkAnswer())#ButtonsfragaBtn = Button(root, text='Nytt tal', command=fraga1)fragaBtn.grid(row=4, column=0)svarButton = Button(root, text='Svar', command=svar1)svarButton.grid(row=4, column=1)quit_bttn = Button(root, text = "Avsluta", command=quit)quit_bttn.grid(row=5, column=0)root.mainloop()

我想你需要的是这个。

P.S:将其放入您的代码中我刚刚在 tkinter 中实现了基本计时器。
