def is_leap_year(year):
    """
        This is how you work out whether if a particular year is a leap year.

    - on every year that is divisible by 4 with no remainder

    - except every year that is evenly divisible by 100 with no remainder

    - unless the year is also divisible by 400 with no remainder


    If English is not your first language, or if the above logic is confusing, try using this flow chart.

    e.g. The year 2000:

    2000 ÷ 4 = 500 (Leap)
    2000 ÷ 100 = 20 (Not Leap)
    2000 ÷ 400 = 5 (Leap!)
    So the year 2000 is a leap year.

    But the year 2100 is not a leap year because:

    2100 ÷ 4 = 525 (Leap)
    2100 ÷ 100 = 21 (Not Leap)
    2100 ÷ 400 = 5.25 (Not Leap)
    """

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


print(is_leap_year(2024))
