Check whether a given year is a leap year or not

There are 3 ways to detect if it is a leap year or not

A leap year is a year that is evenly divisible by 4, except for years that are divisible by 100. However, years divisible by 400 are leap years again.

Method 1

if year % 4 == 0: 

     if year % 100 == 0:

         if year % 400 == 0: 

             print("Leap year") 

         else: 

             print("Not leap year") 

    else: 

         print("Leap year") 

else: 

    print("Not leap year")

Method 2:

year = int(input("Enter a year: ")) result = "Leap year" if (year % 4 == 0 and year % 100 != 0) or (year % 400 == 0) else "Not leap year" print(result)

Method 3:

year = int(input("Enter a year: ")) if year % 400 == 0: result = "Leap year" elif year % 100 == 0: result = "Not leap year" elif year % 4 == 0: result = "Leap year" else: result = "Not leap year" print(result)
