## Python Program to check whether the Year is Leap Year or Not

Write a Python program that has a method called is_leap_year() which accepts the year as its argument and checks whether the year is a leap year or not and displays an appropriate message on the screen.

### Logic of Leap year program:

if the year is divisible by 400 then the year is a leap year

Example: 1600, 2000, 2400, and so on

if the year is divisible by 4 but not by 100 is a leap year

Example:

Leap Year: 2004, 2008, 2012, 2016, 2020, and so on

Not Leap Year: 1800, 1900, 2100 are not leap years

Steps:

1. First we, define the is_leap_year() method, which accepts an argument say a year.

2. Next, we check whether the year is a leap year or not a leap year.

2.1. If Year is a leap year, display a message as the year is a leap year.

2.2. If Year is not a leap year, display a message as the year is not a leap year.

3. Next, read the year from the user and pass the year to the is_leap_year() method.

### Source code of Python Program to check whether the Year is Leap Year or Not

```def is_leap_year(year):
if ((year % 4 == 0 and year % 100 != 0) or year % 400 ==0):
print (year, "is a leap year")
else:
print (year, "is not a leap year")
year = int (input("Enter the year: "))
is_leap_year(year)```

### Output:

Case 1:

Enter the year: 2000
2000 is a leap year

Case 2:

Enter the year: 1600
1600 is not a leap year

Case 3:

Enter the year: 2020
2020 is a leap year
