Calendar module allows to output calendars like program, and provides additional useful functions related to the calendar. Functions and classes defined in Calendar module use an idealized calendar, the current Gregorian calendar extended indefinitely in both directions. In Python, calendar.leapdays() is a function provided in calendar module for simple text calendars. leapdays() method is used to get number of leap years in a specified range of years.

Syntax: leapdays() Parameter: year1, year2: years to get the number of leap years.

Returns: Returns number of leap years in a specified range.

Code #1:

Python3 `

Python program to explain working of leapdays() method

importing calendar module

import calendar

checking number of leap years in range

print(calendar.leapdays(2016, 2022)) print(calendar.leapdays(2001, 2003))

`

Output:

2 0

Code #2: Explaining working of leapdays() method. Below code prints number of leap years and 1st-month calendar of last leap year if any leap year found in given range, otherwise notifies no year is leap.

Python3 `

Python code to demonstrate the working of leapdays()

importing calendar module for calendar operations

import calendar

year1 = 2005 year2 = 2025

calling leapdays() method to verify

val = str(calendar.leapdays(year1, year2)) print("Number of leap years found is % s" % val)

count = 0

checking the condition is True or not

for year in range(year1, year2): val = calendar.isleap(year) if val == True: lyear = year count += 1

if count >= 1:

# print 1st month of first leap year 
calendar.prmonth(lyear, 1, 2, 1) 

Returned False, year is not a leap

else: print("No leap year found")

`

Output:

Number of leap years found is 5 January 2024 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
