python - 对于范围(5)中的 i 和范围(2)中的 k : TypeError: 'bool' object is not iterable

Question

我确信有更好的方法来执行最后一个语句。只是想检查 dayOfWeek 是否在 weekday 或 weekend

中找到

到目前为止我的代码:

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

要检查某个项目是否在列表中，只需使用 in 运算符:

if not(DayOfWeek in weekend or DayOfWeek in weekday):
   print('You did not enter a day!')
