It's not an argument that so far stands in this context. Otherwise a decent amount of the languages most preferred by experienced software engineers would be used more generally by literally anyone else outside that set. And Python then would either be very different, or have far less mind share.

Also keep in mind that a) Python has been around longer than every other "popular" language, and so b) it has a lot of baggage that it has to maintain in order to avoid another 2to3 fiasco.
