--description--

Given an integer year, determine whether it is a leap year.

A year is a leap year if it satisfies the following rules:

• The year is evenly divisible by 4, and
• The year is not evenly divisible by 100, unless
• The year is evenly divisible by 400.

--hints--

is_leap_year(2024) should return True.

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertIs(is_leap_year(2024), True)`)
}})

is_leap_year(2023) should return False.

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertIs(is_leap_year(2023), False)`)
}})

is_leap_year(2100) should return False.

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertIs(is_leap_year(2100), False)`)
}})

is_leap_year(2000) should return True.

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertIs(is_leap_year(2000), True)`)
}})

is_leap_year(1999) should return False.

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertIs(is_leap_year(1999), False)`)
}})

is_leap_year(2040) should return True.

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertIs(is_leap_year(2040), True)`)
}})

is_leap_year(2026) should return False.

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertIs(is_leap_year(2026), False)`)
}})
