I don't write Python, but even so it took about 30 seconds, using the same area of the linked article as a starting point:

    >>> 0 > None
    True

At this point, I fully expect some attempt at a post-hoc rationalization for why Python's choice here is unimpeachable.

python 2 made a rational, well-considered choice, though I do like the python 3 replacement better. Despite its self-consistency, python 2 ended up causing hard-to-find errors (mostly when people accidentally compared "0" with 0 though; it mostly wasn't a problem with None).

In python 2, cross-type comparisons are strictly ordered. So:

    >>> None == 0
    False
    >>> None < 0
    True
    >>> None <= 0
    True
    >>> None > 0
    False

Completely consistent, no special cases, and if you sort() a list containing multiple types, it'll always come out in an unsurprising, consistent order.

Is this python 2 or python 3, afaik that was fixed in python 3.

This error has been fixed in Python 3.

Nope, that's pretty ridiculous!
