python - 根据特定用户输入查找最早的和结尾的内容

Question

我刚刚开始使用 Python，正在尝试一个简单的练习。它是根据用户指定的输入结束程序，然后从输入的一组年龄中查找最大的年龄。我收到了用户输入，但遇到了最旧年龄方面的问题。我哪里出错了？我想我可能不是100%同意“无”这一点。下面是代码:

largest = None

while True:
    name = str(input("What is your name? enter Yvonne to end program."))
    if name.strip() != 'Yvonne':
        age = int(input("Please enter your age"))
    elif name.strip() == 'Yvonne':
        if largest is None or largest < age:
            largest = age
        print("Oldest age is: ",  largest)
        break

我得到的输出是错误的数字被选为最旧的:

您在错误的位置进行了最大测试:

largest = None

while True:
    name = str(input("What is your name? enter Yvonne to end program."))
    if name.strip() != 'Yvonne':
        age = int(input("Please enter your age"))
    
        if largest is None or largest < age:
            largest = age
    else:
        print("Oldest age is: ",  largest)
        break
