Calendar Functions in Python | Set 2(monthrange(), prcal(), weekday()…)

Some of calendar functions are discussed in the Set 1

1. monthrange(year, month) :- This function returns two integers, first, the starting day number of week(0 as monday) , second, the number of days in the month.

2. prcal(year, w, l, c) :- This function also prints the calendar of specific year but there is no need of “print” operation to execute this.

# Python code to demonstrate the working of
# monthrange() and prcal()

# importing calendar module for calendar operations
import calendar

# using monthrange() to print start week day and
# number of month
print ("The start week number and no. of days of month : ",end="")
print (calendar.monthrange(2008, 2))

# using prcal() to print calendar of 1997
print ("The calendar of 1997 is : ")
calendar.prcal(1997, 2,1,6)

Output:

The start week number and no. of days of month : (4, 29)
The calendar of 1997 is : 
                                  1997

3. prmonth(year, month, w, l) :- This function also prints the month of specific year but there is no need of “print” operation to execute this.

4. setfirstweekday(num) :- This function sets the day start number of week.

# Python code to demonstrate the working of
# prmonth() and setfirstweekday()

# importing calendar module for calendar operations
import calendar

# using prmonth() to print calendar of 1997
print ("The 4th month of 1997 is : ")
calendar.prmonth(1997, 4, 2, 1)


# using setfirstweekday() to set first week day number
calendar.setfirstweekday(4)

print ("\r")

# using firstweekday() to check the changed day
print ("The new week day number is : ",end="")
print (calendar.firstweekday())

Output:

The 4th month of 1997 is : 
     April 1997
