Code sample 3 says, "Lists (known as arrays in other languages)", etc. Maybe a small point, but this could be confusing. Python lists are not what are usually meant by "arrays", and in fact Python provides an array module in its standard library (and there is numpy, which provides more array stuff).Since much of the "slow" Python code out there is slow at least in part due to use of inappropriate data types, it might be best not to start beginners off by mixing these things up.
