Python calendar.setfirstweekday()方法 (Python calendar.setfirstweekday() Method)

setfirstweekday() method is an inbuilt method of the calendar module in Python. It works on simple text calendars and sets the first weekday from when the week should start. Here, Monday is 0, incrementing by 1 till Sunday, which is 6. We can also use calendar.day_name where calendar.MONDAY is 0 and calendar.SUNDAY is 6.

setfirstweekday()方法是Python中日历模块的内置方法。 它适用于简单的文本日历，并设置从一周开始的第一个工作日。 在这里，星期一是0，递增1直到星期日是6。我们还可以使用calendar.day_name ，其中calendar.MONDAY为0， calendar.SUNDAY为6。
