迭代python3

Question

我是一名Python3新手..我想弄清楚为什么这不起作用。

我的代码：

#!/usr/bin/env python3


days = ['mon', 'tue', 'wed', 'thur', 'fri', 'sat', 'sun']

hours = []
count = 0

while count < 6:
    print('Please tell me how many hours you slept on:')
    for day in days:
        print(day)
        value = float(input())
        hours.append(value)
        v = sum(value)
        count = count + 1

avg =  ((v) / 7)

print("you slept an average of", round(avg), 'hours')

当我运行这个时，我得到以下错误：“TypeError'flove'对象不可迭代”回溯引用第18行'v = sum（value）'

谢谢

您需要更改

v = sum(value)

到

v = sum(hours)    #sum the list of sleep hrs
