Yes, this has always struck me as one of the weirder corners of python.
There's a bit of magic for comparison operators:

>From the lang ref 5.9:

Formally, if a, b, c, ..., y, z are expressions and opa, opb, ..., opy are
comparison operators, then a opa b opb c ...y opy z is equivalent to a opa b
and b opb c and ... y opy z, except that each expression is evaluated at most
once. 


It's kinda cool, I guess.  Maybe ABC did it first?
