Write a function

  • flmmartins + 4 comments

    The problem's explanation is not clear. I am not an english speaker and the bullet points were not clear enough for me.

    Can that be improved?

    Suggested explanation is bellow:

    In the Gregorian calendar three criteria must be taken into account to identify leap years

    The year can be evenly divided by 4;

If the year can be evenly divided by 100, then it is not a leap year

The year is also evenly divisible by 400 then it is a leap year.

      i agree. maybe this has something to do with my math skil level but, i couldn't understand how to properly figure out that(code below) was an acceptable way to write it.

      year % 4 == 0 and (year % 400 == 0 or year % 100 != 0)

      i would like to understand or have some sort of guide on how to better interpret these questions.

      yes. i too faced the same problem and had to google what a gregorian calendar was and found a page long explanation about how julias caesar invented it... etc etc before actually understanding what it means!

      Agree.

      I am an English speaker and struggled with this definition. It was poorly written.

      My answers are ... 

      def is_leap(year):
    leap = False
    
    if year %4 == 0:
        if year %400 == 0:
            leap = True
        elif year %100 == 0:
            leap = False
        else:
            leap = True
    else:
        leap = False 
    return leap

      or 

      return (year %4 == 0 and year %100 != 0 or year %400 == 0)

        Pretty much what I did, but I don't htink I nested the arguments under if year%4 so it ended up being wrong.
