I am a python newbie, but very experienced programmer.

On the page you have the expression...
-5 != False != True #=> True

This made absolutely no sense to me as a newbie, as I read that expression as being equivalent to
(-5 != False) != True

Which is of course False, Not True.

Until I saw further down the page...
# Comparisons can be chained!

I would suggest you move that expression to the 'chained' section, and then add the explanation...

-5 != False != True #=> True
# chained to be equivalent to   (-5 != False) and (False != True)

Remember this doc is for newbies (like me), and you should not example something before it is introduced.

Thank you
Anthony
