word-autocorrelation code might be too complicated for 20-30 minute breakout room

consider having simpler examples, and have autocorrelation as optional exercises or as "project work" on last day

Word-acf is still a nice type of example because it's somewhat realistic as a scientific problem and maybe corresponds to how people often write python, so maybe best approach is to simplify by removing all the setup/boilerplate and only focus on the two core functions. I.e. use pre-cleaned data etc

i agree, we should extract two separate py files, one for word preprocessing and another for word-acf and use them as examples.

similarly to what's being done to the Julia lesson, the word-acf example can move into a separate exercises episode where all techniques learned can be applied to the same problem
