"Even though Python isn't the fastest language out there, it's likely still faster than the shell command above."
That is going a bit far. By all means use Python. Go ahead and attack people who use the shell. But let's be honest. The shell is faster, assuming one knows how to use it. A similar claim is often made by Python advocates, something along the lines of Python is not slow if one knows how to use it.
The startup time of a Python interpreter is enormous for someone who is used to a Bourne shell. This is what always stops me from using Python as a shell replacement for relatively simple jobs; I have never written a large shell script and doubt I ever will. I write small scripts.
If anyone knows how to mitigate the Python startup delay, feel free to share. I might become more interested in Python.
Anyway, this "jo" thing seems a bit silly. Someone at Google spent their 20% time writing a language called jsonnet to emit JSON. It has been discussed on HN before. People have suggested dhall is a perhaps better alternative.
