title: how to calculate the number of days in leap year
body: <p>Write a program that prompts the user to input a month and a year and then output a message to 
  state how many days are in the given month (note: you will need to consider leap years if the user 
  enters February for the month)</p>
  
  <h2>i used in the first int and input to enter a month and year</h2>
  
  <blockquote>
    <blockquote>
      <p>if (year/400 == 0) and (year/100 != 0) or (year/4 == 0):</p>
    </blockquote>
  </blockquote>
  
  <pre><code>print( "this year is a leap year: ")
  
  if ( month == "December" or  month == "January" or month == "March" or  month == "May" or month  == "July" or  month == "August" or month == "October" ):
      print ("days are: 31")
  
  elif ( month == "April" or month == "June" or month == "September" or  month == "November"):
      print ("days are: 30")
  
  elif ( month == "February" ):
      print ("days are: 29")
  </code></pre>

    <blockquote>
      <p>else:</p>
    </blockquote>

  <pre><code>print( "this year is not a leap year: ")
  
  if ( month == "December" or  month == "January" or month == "March" or  month == "May" or month == "July" or  month == "August" or month == "October" ):
      print ("days are: 31")

  <p>the code doesn't work in the correct, it only work with else , so if somebody has an idea about the error 
  I think the error in first condition ( if year/400 == 0 ).......</p>
