Wow! If only one could write it as following: <pre class='brush: python'>middle=lambda s:s[-(n:=len(s) // 2 + 1) : n] </pre> It would be a nice self-referential twist, wouldn't it? ))

I tried to make it as short as possible, for the <a href="https://py.checkio.org/mission/middle-characters/publications/category/puzzle/">Creative</a> category. That's the reason for lambda, one-letter names and the absence of spaces.

Got it! But have a look at <pre class='brush: python'>middle('middle=lambda s:s[-(n:=len(s) // 2 + 1) : n]') </pre>
