Yes. I was wondering about that after I wrote the two client versions! Lisp is really easy to read. I not write yet the docstrings, but still is easy to understand. As much as I enjoy reading code in Python, Lisp is also in my heart.
What ? maybe I'm stupid, but to me the python version seems a a lot more readable. It's only me ? (maybe because I don't know lisp, but neither python, so should be the same)
What programming languages do you know? If you know one or some algol-like one their syntax is very similar to each other and very different from lisp-like langs.
You can use a library like https://github.com/fiddlerwoaroof/format-string-builder to make formatted output more readable. But, in general, format strings are like regular expressions: at first they look like alien technology and then, after using them a while, they become quite legible.
