为什么我的变量即使加1也不改变？

Question

我刚完成我的代码，它有一个问题： 事实上，即使每次用户输入正确答案时，我都会向其中添加1，但其中一个变量的值并没有改变。我模拟了这个结果，并注意到在最后，当我调用我的变量时，它显示为0。 代码要求用户在40秒内回答20次乘法运算，最后，它会告诉用户他跳过了多少个问题，他回答了多少个好问题

import time

seconds = 40


def Timer(seconds, i):
    print("Start timer : 40s")
    for i in range(seconds):
        seconds -= 1
    if seconds == 0:
        print("End")
    time.sleep(1)

Python 3中的input()返回一个字符串，您正在将答案与数字进行比较。将它们与字符串进行比较，您应该可以。例如：

if rep1 == '49':
    # Here-^ ^
    rep2 = input(phraseRep + " " + multi2)
    goodAnswers += 1
