Do you know what is PEP8?

Python code should use snake_case for naming variables and functions.

but years divisible by 400 are leap years

Hi,

• missing sample tests
• the function identifier should be in snake_case
• the problem isn't fully specified: what does mean "ignore" if not in the list? remove? keep at original position? put at the end? the beginning?
• this kind of task has already been done

if you're interested in authoring kata, you should dive in the documentation before your next try.

cheers
