Python calendar module | isleap() method

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.isleap() is a function provided in calendar module for simple text calendars.

Code #1:

# Python program to explain working of isleap() method

# checking whether given year is leap or not
print(calendar.isleap(2016))
print(calendar.isleap(2001))

Output:

True
False

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
else:
    print("% s is not a leap year" % year)
