I'm picking up Python in my new job, and one thing that I dearly miss from Perl is an equivalent to Dist::Zilla (https://metacpan.org/release/Dist-Zilla). After a bit of initial setup (name, PAUSE account, etc), publishing is about as easy as

   dzil new My::Module
   <build library>
   dzil test #Make sure the build and tests go okay
   <set version and add changes to changefile>
   dzil publish
