It isn't a necessary evil when it isn't necessary. If you have isolation (like virtualenv) then each app gets exactly what it needs. Life is too short to waste

It isn't a necessary evil when it isn't necessary. If you have isolation (like virtualenv) then each app gets exactly what it needs. Life is too short to waste it trying to make every single bit of Python use the same versions of dependencies, pinning the version in the package manager, etc. The universe does not revolve around lazy sysadmins
