 Comparing Sequences and Other Types
 ===================================
-
-Sequence objects may be compared to other objects with the same sequence type.
-The comparison uses *lexicographical* ordering: first the first two items are
-compared, and if they differ this determines the outcome of the comparison; if
-they are equal, the next two items are compared, and so on, until either
-sequence is exhausted. If two items to be compared are themselves sequences of
-the same type, the lexicographical comparison is carried out recursively.  If
-all items of two sequences compare equal, the sequences are considered equal.
-If one sequence is an initial sub-sequence of the other, the shorter sequence is
-the smaller (lesser) one.  Lexicographical ordering for strings uses the Unicode
-code point number to order individual characters.  Some examples of comparisons
-between sequences of the same type::
+Sequence objects typically may be compared to other objects with the same sequence

    (1, 2, 3)              < (1, 2, 4)
    [1, 2, 3]              < [1, 2, 4]
