Syntax: isleap()
year: Year to be tested leap or not.

Returns: Returns True if the year is a leap year, otherwise False.

Code #1:

# Python program to explain working of isleap() method
# importing calendar module
import calendar
# checking whether given year is leap or not




Code #2: Explaining working of isleap() method.

Below code prints 4th months calendar if given year is year, otherwise notifies year is not leap.

# Python code to demonstrate the working of isleap() 
# importing calendar module for calendar operations 
import calendar 
year = 2017
# calling isleap() method to verify
val = calendar.isleap(year)
# checking the condition is True or not
if val == True:
    # print 4th month of given leap year 
    calendar.prmonth(year, 4, 2, 1
# Returned False, year is not a leap
