如何制作一个接受输入并总结+在终止和打印结果之前计算平均值的聊天机器人？

Question

我是编程新手，刚开始学习 Python 课程。我一直在浏览课程 material 和在线查看是否有我遗漏的东西，但找不到任何东西。

我的任务是制作一个聊天机器人，它接受输入并汇总输入，同时计算平均值。它应该接受所有输入，直到用户写入 "Done"，然后终止并打印结果。

当我尝试运行时：

total = 0
amount = 0
average = 0
inp = input("Enter your number and press enter for each number. When you are finished write, Done:")

while inp:
    inp = input("Enter your numbers and press enter for each number. When you are finished write, Done:")
    amount += 1
    numbers = inp
    total + int(numbers)
    average = total / amount
    if inp == "Done":
        print("the sum is {0} and the average is {1}.". format(total, average))

我收到此错误：

Traceback (most recent call last):
  File "ex.py", line 46, in <module>
    total + int(numbers)
ValueError: invalid literal for int() with base 10: 'Done'

通过搜索我收集到的论坛，我需要将 str 转换为 int 或类似的东西？如果还有其他问题需要修复，请告诉我！

似乎问题是当用户键入 "Done" 然后行 int(numbers) 正试图将 "Done" 转换为一个整数，但这是行不通的。一个解决方案是移动您的条件

if inp == "Done": print("the sum is {0} and the average is {1}.". format(total, average))

更高，就在 "inp = " 作业下方。这将避免 ValueError。还要添加一个 break 语句，以便在有人键入 "Done"

时立即跳出 while 循环

最后我认为你在添加到 total 变量时缺少一个 = 符号。

我想这就是你想要的：

while inp:
    inp = input("Enter your numbers and press enter for each number. When you are finished write, Done:")
    if inp == "Done":
        print("the sum is {0} and the average is {1}.". format(total, average))
        break
    amount += 1
    numbers = inp
    total += int(numbers)
    average = total / amount
