this is useless. In the python interface they are obviously lists. Is the author arguing that cpython implements them as C arrays? I don't know because the terms weren't defined.
If the author believes clarity will arise from pedantry, maybe he should start with wikipedia
> In computer science, a list or sequence is an abstract data type that implements a finite ordered collection of values, where the same value may occur more than once.
