You are right. But the normal application of Python is in circumstances, where you are not under such pressure anyway and flexibility and ease of use is more a requirement than having maximum speed or minimal memory requirements. And of course it is particularly the CPython implementation that I described ... but CPython is still the implementation that is used most and the one where most enhancements, libraries and so exist. Other implementations might do better in many ways, but what made Python great, is still available in its original form, the CPython environment.
