I'm still just a Python novice, so obviously I didn't write this code originally; I'm just transcribing it from a text file into Vim to demonstrate how easily and fluently code can be written with steno. It's not primarily about speed, but about chunking commands and words into single strokes, as opposed to breaking them down into individual letters and typing each letter out one by one as in qwerty. Also notice how simple error correction is; an incorrect word is deleted with a single stroke.
