Calendar Functions in Python | Set 1( calendar(), month(), isleap()…)
Python defines an inbuilt module “calendar” which handles operations related to the calendar.
Operations on the calendar :
1. calendar(year, w, l, c):- This function displays the year, the width of characters, no. of lines per week, and column separations.
2. firstweekday() :- This function returns the first week day number. By default 0 (Monday).
Python3
# Python code to demonstrate the working of # calendar() and firstweeksday() # importing calendar module for calendar operations import calendar # using calendar to print calendar of year # prints calendar of 2012 print ( "The calendar of year 2012 is : " ) print (calendar.calendar( 2012 , 2 , 1 , 6 )) #using firstweekday() to print starting day number print ( "The starting day number in calendar is : " ,end = "") print (calendar.firstweekday()) |
Output:
The calendar of year 2012 is : 2012 January February March Mo Tu We Th Fr Sa Su Mo Tu We Th Fr Sa Su Mo Tu We Th Fr Sa Su 1 1 2 3 4 5 1 2 3 4 2 3 4 5 6 7 8 6 7 8 9 10 11 12 5 6 7 8 9 10 11 9 10 11 12 13 14 15 13 14 15 16 17 18 19 12 13 14 15 16 17 18 16 17 18 19 20 21 22 20 21 22 23 24 25 26 19 20 21 22 23 24 25 23 24 25 26 27 28 29 27 28 29 26 27 28 29 30 31 30 31 April May June Mo Tu We Th Fr Sa Su Mo Tu We Th Fr Sa Su Mo Tu We Th Fr Sa Su 1 1 2 3 4 5 6 1 2 3 2 3 4 5 6 7 8 7 8 9 10 11 12 13 4 5 6 7 8 9 10 9 10 11 12 13 14 15 14 15 16 17 18 19 20 11 12 13 14 15 16 17 16 17 18 19 20 21 22 21 22 23 24 25 26 27 18 19 20 21 22 23 24 23 24 25 26 27 28 29 28 29 30 31 25 26 27 28 29 30 30 July August September Mo Tu We Th Fr Sa Su Mo Tu We Th Fr Sa Su Mo Tu We Th Fr Sa Su 1 1 2 3 4 5 1 2 2 3 4 5 6 7 8 6 7 8 9 10 11 12 3 4 5 6 7 8 9 9 10 11 12 13 14 15 13 14 15 16 17 18 19 10 11 12 13 14 15 16 16 17 18 19 20 21 22 20 21 22 23 24 25 26 17 18 19 20 21 22 23 23 24 25 26 27 28 29 27 28 29 30 31 24 25 26 27 28 29 30 30 31 October November December Mo Tu We Th Fr Sa Su Mo Tu We Th Fr Sa Su Mo Tu We Th Fr Sa Su 1 2 3 4 5 6 7 1 2 3 4 1 2 8 9 10 11 12 13 14 5 6 7 8 9 10 11 3 4 5 6 7 8 9 15 16 17 18 19 20 21 12 13 14 15 16 17 18 10 11 12 13 14 15 16 22 23 24 25 26 27 28 19 20 21 22 23 24 25 17 18 19 20 21 22 23 29 30 31 26 27 28 29 30 24 25 26 27 28 29 30 31 The starting day number in calendar is : 0
3. isleap (year):- This function checks if the year mentioned in the argument is a leap or not.
4. leapdays (year1, year2):- This function returns the number of leap days between the specified years in arguments.
Python3
# Python code to demonstrate the working of # isleap() and leapdays() # importing calendar module for calendar operations import calendar # using isleap() to check if year is leap or not if (calendar.isleap( 2008 )): print ( "The year is leap" ) else : print ( "The year is not leap" ) #using leapdays() to print leap days between years print ( "The leap days between 1950 and 2000 are : " ,end = "") print (calendar.leapdays( 1950 , 2000 )) |
Output:
The year is leap The leap days between 1950 and 2000 are : 12
5. month (year, month, w, l) :- This function prints the month of a specific year mentioned in arguments. It takes 4 arguments, year, month, width of characters and no. of lines taken by a week.
Python3
# Python code to demonstrate the working of # month() # importing calendar module for calendar operations import calendar # using month() to display month of specific year print ( "The month 5th of 2016 is :" ) print (calendar.month( 2016 , 5 , 2 , 1 )) |
Output:
The month 5th of 2016 is : May 2016 Mo Tu We Th Fr Sa Su 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
