For those that think migrating from python2 to 3 is easy: no. You’ve clearly never tried to migrate different companies/environments. Sure, the code now runs in the py3 interpreter, but guess what!? That was the easy part! Now go hunting down Byzantine build scripts and environments to find out how it was deployed and tested. Tested lol? Ugh and guess what? The code base has commits that we’re never deployed to prod. What do you do now? You basically own a service that hasn’t been deployed in 4 years and a branch that was never deployed ever.
