Python 为什么我的变量即使加1也不改变？

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)

Python3中的输入返回一个字符串，并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：

如果rep1==“49”： 这里-^-^ rep2=inputphraseRep++multi2 好答案+=1

这是什么版本的Python？是Python 3.8。2@marw4neinput返回Python 3中的字符串。rep1==49形式的所有比较结果都将计算为False。对于将来的问题，请仅提供问题的一部分，而不是粘贴整个项目。那么，如何使其返回int？对此表示抱歉，将执行以下操作：
