Wow! That's excellent piece!

this is pretty awesome! the use of `or` to perform your sort before calculating the mean is neat and the +/- indexing trick is fun, but the bitwise inversion of -len(d) was incredibly tricky! I hope you don't write production code this sneaky!

~-d is equivalent to d-1 (and -~d == d+1). If you want +/- indexing, have this (shorter by 1 character by the way! :D) <pre class='brush: python'>checkio=lambda d:d.sort()or(d[~len(d)//2]+d[len(d)//2])/2 </pre>

Now I make 56 chars code :-) See <a href="http://www.checkio.org/mission/median/publications/Sim0000/python-3/56-chars/">here</a>. using def is the only difference.

List but not the least
