We use Nix which is much nicer than pyenv/virtual environment, but it's still a pain compared to Go. This is mostly due to Python's runtime model, and maybe also the tendency for Python applications to have very tall, broad dependency graphs.

Working with nix is also not very easy; docker might fare better here, but probably just a lateral move. In any case, Go outclasses Python on deployments. Also, my company is looking into compiling Python as a means of code obfuscation; Go compiles by default, which (modulo stripping) is probably enough obfuscation for our purposes.
