如何修复我的工作日，以在周六和周日输出特定信息。从周一到周五，人们都在工作，周六到周日是周末

Question

这是模拟的一部分。我的今天作为当前纪元，它总是从 0 开始。我当前的代码如下：

    is_weekend = current_day % 5 == 0 or current_day % 6 == 0

    if is_weekend:
        print("people are at home")
    else:
        print("people are at work")

    for person in people:
        if is_weekend:
            person.location = "Home"
        else:
            person.location = "Work"

但是，当我进入计划的第二周工作时，周六他们在家，但周日他们又回到工作岗位。我以为使用 % 会起作用，但似乎有问题。

问题是我们有 7 days 而您检查 multiples of 5 and 6。按照这种逻辑，10th day 将与 5th day 是同一工作日，但这是错误的 - 一周后是 12th day。此外，0 % x returns 0 因此在使用模运算符时必须考虑到这一点。在我们的例子中，这无关紧要，因为我们不再检查 0。

weekdays = ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun'];
for i in range(0, 14):
    day_of_week = i % 7;
    is_weekend = day_of_week == 5 or day_of_week == 6;
    print('The', i, 'day is a', weekdays[day_of_week], '=> is weekend?', is_weekend)

您必须检查本周的 5 和 6 的剩余部分，因为一周有 7 天。

The 0 day is a Mon => is weekend? False
The 1 day is a Tue => is weekend? False
The 2 day is a Wed => is weekend? False
The 3 day is a Thu => is weekend? False
The 4 day is a Fri => is weekend? False
The 5 day is a Sat => is weekend? True
The 6 day is a Sun => is weekend? True
The 7 day is a Mon => is weekend? False
The 8 day is a Tue => is weekend? False
The 9 day is a Wed => is weekend? False
The 10 day is a Thu => is weekend? False
The 11 day is a Fri => is weekend? False
The 12 day is a Sat => is weekend? True
The 13 day is a Sun => is weekend? True

这就是模的工作原理（在本例中）：

0 % 7 => 0 / 7 => remainder is 0
1 % 7 => 1 / 7 => remainder is 1
2 % 7 => 2 / 7 => remainder is 2
...
7 % 7 => 7 / 7 => remainder is 0
8 % 7 => 8 / 7 => remainder is 1
9 % 7 => 9 / 7 => remainder is 2

模运算符（在这种情况下）会告诉我们当我们将第一个数字一次又一次地除以 7 时还剩下多少......直到我们得到一个小于正确数字（即 7）的数字这将是模运算符的结果。

300 / 7 = 42.8571 ... 42.8571 / 7 = 6.1224

但是

300 % 7 = 6 <=> (int) (300 / 7) = 6

在没有得到浮点数的情况下，我们能得到多少？它是 294 因为 42 * 7 = 294、6 is missing to 300 和 6 is smaller than 7, therefore, remainder 6
