乘法程序

Question

我正在为我的妹妹在python 2.7.5中制作这个乘法程序，我不知道如何计算正确的答案。这是代码：

import easygui
for i in [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]:
    answer = easygui.enterbox("What is " + str(i) + ' times 8?')
    if int(answer) == i * 8:
        easygui.msgbox("That is correct!")
    else:
        easygui.msgbox("Wrong!")

Answer 1

为什么不加一个变量来为你计算？

import easygui
correct_answers = 0 # start with none correct
for i in [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]:
    answer = easygui.enterbox("What is " + str(i) + ' times 8?')
    if int(answer) == i * 8:
        easygui.msgbox("That is correct!")
        correct_answers += 1 # increment
    else:
        easygui.msgbox("Wrong!")

您可以通过将基数设为变量来改进程序，并使用Python的str.format()而不是添加：

base = 8
...
    answer = easygui.enterbox("What is {0} times {1}?".format(i, base))
    if int(answer) == i * base:
        ...
