Directly inspired by the classic C coding competition, the IOCCC, the IOPCC is now accepting submissions. This is my first time running a competition, so there will likely be some issues in this first year. Tentative plan for submissions end-date is outlined on https://pyobfusc.com/#submit.
As far as I know, the requirement of the IOCCC has always just been to submit any obfuscated C program. A submitted program can do something interesting, or something ordinary in an interesting way, but there's no specific constraint on what it does.
You might be confusing the IOCCC with the Underhanded C Contest, in which the goal was to do some particular task, but also subvert it in a non-obvious way: http://www.underhanded-c.org/
Thanks! I'm very excited to see it. You can submit any Python program as long as it produces an output of some kind without human intervention. More details are here: https://pyobfusc.com/#rules
