@ -661,9 +661,8 @@ operators, not just comparisons.
The comparison operators ``in`` and ``not in`` check whether a value occurs
(does not occur) in a sequence. The operators ``is`` and ``is not`` compare
whether two objects are really the same object; this only matters for mutable
objects like lists. All comparison operators have the same priority, which is
lower than that of all numerical operators.
whether two objects are really the same object. All comparison operators have
the same priority, which is lower than that of all numerical operators.
Comparisons can be chained. For example, ``a < b == c`` tests whether ``a`` is
less than ``b`` and moreover ``b`` equals ``c``.
