I implemented a vimgolf client in Python.
The source code is available on GitHub:
https://github.com/dstein64/vimgolf
The user interface is similar to the official vimgolf client, with a few additions inspired by vimgolf-finder.
The package is available on PyPI, the Python Package Index. It can be installed with pip.
$ pip3 install vimgolf
