I use Python a few times a month for some simple scripting usually. Every time I have to look up how to use `range()` correctly, usually because I forgot if it's inclusive or exclusive. Academics that are used to Matlab or Julia will also have to look up if it starts at 0 or 1.

Furthermore, it's obvious what `time()` does in this context, but if I was writing this code I would _absolutely_ have to look up the correct time function to use for timing a function.
