Sure! This might be even lighter than what you're expecting.

I'm not sure how to get HN to format my code correctly, so here's a gist. It has two functions, one that generates a list of dicts with fake people data, and another that does sentiment analysis of tweets. Both are two lines of code. https://gist.github.com/jlowin/ae22fb7ac1788f066f809d2b8f573...

You can get more complex than this but hopefully this shows the idea: define your inputs, define your outputs, give it a descriptive docstring (as descriptive as you want!), and call it.
