I agree with what you say and not a Python fanatic but this high level language stigmas catch my attention. If you try to implement your own, let's say, intersection of sets you will probably get at most the same performance as Python using a reasonable amount of time. I guess my point is that seeing the comment of Python in a thread like this can also be confusing. Bad (or maybe I should say "not appropriate for your use") implementations can exist in any language.
