2016
Output
Leap year

Required to Know

Use of Variables, Use of different operators like assignment or arithmetic operators, Use of functions like print(), and input(), Use of If-else, and Use of Data types.

Steps

• Take the year as input from the user.

• The condition of the leap year will go in this format: -

  • If the year is divisible by 4 and not 100 then it is not a leap year.

  • Similarly, if the year is divisible by 400 then it is a leap year.

Program

# This code checks if a year is a leap year.

# Get the year from the user.
year = int(input("Enter the year: "))

# Check if the year is divisible by 4.
if year % 4 == 0:

  # If the year is divisible by 4, it is a leap year unless it is divisible by 100.
  if year % 100 != 0:

    # If the year is not divisible by 100, it is a leap year.
    print("Leap year")
  else:

    # If the year is divisible by 100, it is not a leap year unless it is divisible by 400.
    if year % 400 == 0:

      # If the year is divisible by 400, it is a leap year.
      print("Leap year")
    else:

      # If the year is not divisible by 400, it is not a leap year.
      print("Not a leap year")
else:

  # If the year is not divisible by 4, it is not a leap year.
  print("Not a leap year")
