Alessandro Amici - Solving the web most popular code shortening competition in Python. “Code shortening” is the “sport” where participants strive to achieve the shortest possible source code that solves a programming problem by exploiting all the tricks and quirks of the language. The [SIZECON on SPOJ] is one of the oldest and most popular code shortening problems on the web with a bizarre twist, only character above ASCII value 32 are counted for the penalty. During the talk we will take a journey into some frightening depths of the Python language in order to write shorter and shorter solutions to SIZECON until, exploiting a number of truly mind-blowing tricks, we will reach the current record solution of 28 characters (above ASCII 32!). I promise I’ll show you the most obfuscated, contrived and sick python code you have ever seen and (hopefully!) will ever see. I invite participants to give [SIZECON] a try and check their score against the [Python2] and [Python3] SPOJ rankings.
