Detailed explanation of the use of Python calendar module

calendarThe functions of the module are all related to the calendar, providing some operation methods for dates and methods for generating calendars.

Provided in the calendar module There are three major categories:

1. calendar.Calendar(firstweekday=0)

This class provides many generators, such as weekday generators, a certain month calendar Generator

2. calendar.TextCalendar(firstweekday=0)

This class provides a method to generate calendar string by month and year.

3. calendar.HTMLCalendar(firstweekday=0)

Similar to TextCalendar, but it generates an HTML format calendar

The calendar module itself also provides many methods:

1 calendar.calendar(year,w=2,l=1,c=6)

Returns a year calendar in multi-line string format, with 3 months per line, and the interval is c. Daily width interval is w characters. The length of each line is 21* W+18+2* C. l is the number of lines per week.

Case:

{

Return the calendar of one year

calendar.calendar(2011,w=2,l=1,c=2)

}

2 calendar.firstweekday( )

Returns the current weekly starting day setting. By default, 0 is returned when the caendar module is first loaded, which is Monday.

Case:

{

calendar.setfirstweekday(calendar.SUNDAY)

The default first day of the week is Monday, here it is changed to Sunday

'MONDAY', 'SATURDAY', 'SUNDAY', 'THURSDAY', 'TUESDAY', 'TextCalendar', 'TimeEncoding', 'WEDNESDAY'

}

3 calendar. isleap(year)

returns True if it is a leap year, otherwise false.

Case:

{

calendar.isleap(2017)

}

4 calendar.leapdays(y1,y2)

Returns the total number of leap years between Y1 and Y2.

Case:

{

calendar.leapdays(2000,2020); ## 5

}

5 calendar.month (year,month,w=2,l=1)

Returns a year and month calendar in multi-line string format, with two lines of title and one line for each week. Daily width interval is w characters. The height of each row is 7* w+6. l is the number of lines per week.

Case:

{

Returns the calendar of a certain month, the return type is string

calendar.month(2011, 11,w =4,l=2);

}

6 calendar.monthcalendar(year,month)

Returns a single-level nested list of integers. Each sublist holds an integer representing a week. Dates outside Year, month, and month are all set to 0; days within the range are represented by the day of the month, starting from 1.

Case:

{

calendar.monthcalendar(2017,3)

##[[0, 0, 0, 1, 2, 3 , 4], [5, 6, 7, 8, 9, 10, 11], [12, 13, 14, 15, 16, 17, 18],

[19, 20, 21, 22 , 23, 24, 25], [26, 27, 28, 29, 30, 31, 0]]

}

7 calendar.monthrange(year,month)

Return two integers. The first is the date code of the day of the week of the month, and the second is the day code of the month. Days range from 0 (Monday) to 6 (Sunday); months range from 1 to 12.

Case:

{

calendar.monthrange(2017,3);##(2, 31)

}

8 calendar.prcal(year,w=2,l=1,c=6)

is equivalent to print

calendar.calendar(year,w,l,c).

Case:

{

calendar.prcal(2017,w=2,l=1,c=6)

}###

9 calendar.prmonth(year,month,w=2,l=1)

Equivalent to print calendar.calendar(year,w,l,c).

Case:

{

calendar.prmonth(2017,3,w=2,l=1)

}

10 calendar.setfirstweekday(weekday)

Set the starting day code of each week. 0 (Monday) to 6 (Sunday).

Case:

{

calendar.setfirstweekday(calendar.SUNDAY)

The default first day of the week is Monday, here it is changed to Sunday

'MONDAY', 'SATURDAY', 'SUNDAY', 'THURSDAY', 'TUESDAY', 'TextCalendar', 'TimeEncoding', 'WEDNESDAY'

}

11 calendar. timegm(tupletime)

is the opposite of time.gmtime: it accepts a time tuple and returns the time at that moment (the number of floating-point seconds elapsed since the 1970 epoch).

Case:

{

calendar.timegm(time.localtime

(time.time()))

1489616168

12 calendar.weekday(year,month,day)
