Python date.isocalendar()方法 (Python date.isocalendar() Method)

date.isocalendar() method is used to manipulate objects of date class of module datetime.

date.isocalendar()方法用于操作模塊datetime的日期類的對象。

It uses a date class object and returns a 3-tuple (ISO year, ISO week number, ISO weekday).

它使用日期類對象并返回一個三元組(ISO年，ISO周號，ISO周日)。

Most of the date and time calendar follow the Gregorian calendar. The ISO calendar is a widely used variant of the Gregorian one. The ISO year consists of 52 or 53 full weeks, and where a week starts on a Monday and ends on a Sunday. The first week of an ISO year is the first (Gregorian) calendar week of a year containing a Thursday. This is called week number 1, and the ISO year of that Thursday is the same as its Gregorian year.
For example, 2004 begins on a Thursday, so the first week of ISO year 2004 begins on Monday, 29 Dec 2003 and ends on Sunday, 4 Jan 2004:

大多數日期和時間日歷都遵循公歷。 ISO日歷是公歷之一的廣泛使用的變體。 ISO年度包括52或53個整周，其中一個星期從星期一開始，在星期日結束。 ISO年的第一周是包含星期四的一年中的第一個(格里高利歷)日歷周。 這稱為第1周，該周四的ISO年與其公歷年相同。
例如，2004年從星期四開始，因此ISO 2004年的第一周從2003年12月29日星期一開始，到2004年1月4日星期日結束：

Weekday number for Monday is 1 while incrementing by 1 for the coming days.

星期一的工作日數為1，而接下來的幾天則增加1。
