对于范围（5）中的i和范围（2）中的k:TypeError:“bool”对象不是iterab

Question

我相信有更好的方法来做最后的陈述。只是想看看dayOfWeek是在weekday还是weekend中找到的

到目前为止我的代码是：

dayOfWeek = input('What day is it?\n')

weekDay = ['Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday']
weekend = ['Saturday', 'Sunday']


for i in range(5) and k in range(2):
    if dayOfWeek != weekDay[i] and dayOfWeek != weekend[k]:
        print("You didn't enter a Day of the week")

Answer 1

您的尝试被解析为

for i in (range(5) and (k in range(2))):

似乎k是以前分配的range(5)本身是真实的，因此and表达的结果就是比较的真实性

将列表（或者更确切地说，它们的迭代器）与itertools.chain链接在一起，然后使用not in：

from itertools import chain

if dayOfWeek not in chain(weekDay, weekend):
    print("You didn't enter a Day of the week")
