In "python paradox", 'knows python' is an indication that the developer is interested in something technically interesting but otherwise impractical. Hence, it's a 'paradox' that you end up practically better off by selecting for something impractical.
These days, Python is surely a practical choice, so doesn't really resemble the "interested in something technically interesting but impractical".
