TLDR Python 3 isn ' t compatible with python 2 , nor should anyone expect it to be . major version change , smartassThat ' s not even true , with some shims e . g . and the features the later revisions of P 3 readded e . g . u prefix there is in fact a common subset of P 2 and P 3 , and you can write singlesource packages compatible with both . In fact after some waffling around that ' s what most library authors have settled on , it ' s a bit of a pain in the ass but still way better than having to deal with completely separate codebases . <| sep |> HR wasn ' t really good until this episode . Now he ' s starting to get better . <| sep |> 3 MeOPCE would probably be the most populair one if it was less expensive . I wouldn ' t mind using this one every day , not a valid argument but stil . DCK and OPCE are more enjoyablesuitable for holing but less so for lower recreational dosages . Very similair substances when it comes to their effects on their own , aside from onset and duration in my experience . 3 MeOPCP is also certainly a gem but relatively unsuitable for higher dosages or frequent usage , less so then other dissociatives anyways . It ' s too ' activating ' and ' manic ' for these means in my opinion . 3 MeOPCP is easy to abuse and when you do it can be pretty devastating .
