There is definitely a substantial number of people who know Python and have had little to no exposure to C or C++. To the point where they'd really rather see something like this presented in a language they're familiar with and that they can try out in an environment they've already got setup.

There's no harm in having many articles on a given subject (think how many monad posts there are) - if you dislike one you don't have to read it, there's plenty of other interesting stuff out there :-)
