Article not worth reading. Would have been much better as a quick tip. "Quick tip: if you need to loop through an array in Python, do it this way instead..."
I see numerous issues with the loop, for example, hash key lookups on 'Lat' and 'Long' for every iteration.
CPython, which is the standard, most common implementation, uses bytecodes (and so does Java). There's nothing preventing one from generating machine code from a Python source. Some of Python's dynamic features are mandated from the spec, and there are limits on how fast that can be. But that has nothing to do with "being an interpreted language".
