“或”的问题在“day.weekday() == 5 或 6”中
为什么在这种情况下使用“或”运算符会产生不同的结果？为什么我必须写两次 day.weekday() 而不仅仅是 == 5 或 6
这是有效的选项
if day.weekday() == 5 or day.weekday() == 6:
这是给出不同结果的选项
if day.weekday() == 5 or 6:
Why does using the 'or' operator give different results in this case? Why must I write the day.weekday() twice rather than just == 5 or 6
This is the option that works
if day.weekday() == 5 or day.weekday() == 6:
This is the option that gives a different result
if day.weekday() == 5 or 6:

或者语句的工作方式如下：
通过说：
代码认为您暗示 6 是一个条件，如果您尝试在星期六打印某些内容（因为星期六是一周的第 6 天），则不会打印任何东西。希望这对您有所帮助，如果没有，请发表评论，否则您需要其他帮助。
Or statements work as such:
By saying:
The code thinks that you are implying that 6 is a condition, which if you are trying to print something if it's a Saturday (since saturday is the 6th day of the week), you won't get anything printed. Hope this helps, leave a comment if it doesn't, or you need additional help.
它给出了不同的结果，因为“day.weekday() == 5”和“6”是分开计算的。它不会给出错误，因为任何非 0 的数字都会计算为“True”。
更好的写法是：
It gives a different result because "day.weekday() == 5" and "6" are being evaluated separately. It doesn't give you an error because any number that is not 0 evaluates to "True".
The better way to write this would be:
