Allowing to compress code this much is the goal of golfing languages (such as 05AB1E (or osabie) or Pyth (not Python)). The code golf stack exchange forum contains a lot of programming challenges where the goal is to write the shorest program (in bytes) that does what the challenge asks, and some answers are truly impressive, with somewhat non-trivial algorithms being implemented in as few as 4 bytes (in extreme cases). Granted, these are programming challenges and not production code to be deployed, and some golfing languages are designed for a specific kind of task or algorithm that may let us think that the algorithm was actually pre-implemented in the language (and sometimes it is kinda true), but still, worth taking a look at it.
