Um... have you actually read that article? He doesn't mention "for loops" at
all, or any other kind of loop, for that matter. Neither does he say anything
about the appearance of the comparison operators.
He does talk about the values of the range endpoints, and mentions notations
for ranges and array lower bounds in various languages. Python has equivalents
of those -- sequence indexes, range() parameters, slice indexes, etc. Most of
what he says applies perfectly well to Python.
