Nitpicking, but to conform with PEP-8 this should be rewritten from <pre class='brush: python'>checkio = lambda a: [i for i in a if a.count(i)>1] </pre> to <pre class='brush: python'>checkio = lambda a: [i for i in a if a.count(i) > 1] </pre>

A comment for two missing spaces ^^ Well the pep8 does not like named lambda functions too. They are mainly for simple functions we use in arguments like <pre class='brush: python'>some_list.sort(key=lambda x: x[1]) # instead of doing def f(x): return x[1] some_list.sort(key=f) </pre> PEP8 talk about good practices, and it is great, I use a linter in my IDE, but there are not god rules either, I like short lambda functions.

The Use Of Best Practices make difference in formatting the code and improves readability and makes it more editable So Yeah Following PEP8 Obliges you to document your code and add a lot of comments in order to have a fully documented code and written in what's known as a "pythonic" way, Without forgetting that it strictly push you to follow naming conventions <a href="https://namingconvention.org/python/">Some Naming Conventions</a>. This doesn't mean bypassing PEP8 you are expelled from python's mercy, But to many restrictions are sometimes a headache -_- But one's must make his life easier and follow what's a must and ignores what is secondary. As William Shakespeare said: <blockquote> Examining the most trivial behavior may drive you into insanity, So ignore once and miss twice. </blockquote> Big Up to you all. See You Later Guys.
