Question

我正在尝试在Tkinter中编写一个测验应用程序，到目前为止我已经得到了下面的代码 - 但即使我输入正确的答案，它总是会出现错误。

import tkinter
from random import randint

score = 0

def question():
    global number1
    global number2
    number1 = randint(1,12)
    number2 = randint(1,12)
    question = tkinter.Label(window, text="What is " + str(number1) + "x" + str(number2) + " ?")
    question.pack()

def Validate():
    global score
    global number1
    global number2
    ans = number1 * number2
    if answer == number1*number2:
        score = score+1
        print('True')
    else:
        score = score-1
        print('False')

window = tkinter.Tk()
question()
answer = tkinter.Entry(window)
submit = tkinter.Button(window, text = "Submit", command=Validate)
answer.pack()
submit.pack()
window.mainloop()

正如Rawing评论的那样，代码将tkinter.Entry对象与对象进行比较。

您可以使用Entry.get()将输入的文字输入到条目中，您可以使用int将字符串转换为int()对象：

def Validate():
    global score
    answer_string = answer.get()
    try:
        answer_value = int(answer_string)
    except ValueError as e:
        print(e)
        return

    if answer_value == number1 * number2:
        score -= 1
        print('True')
    else:
        score += 1
        print('False')

Tkinter中的测验，修复if ... else循环
