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::

Some examples of comparisons between sequences of the same type::
(1, 2, 3) < (1, 2, 4)
[1, 2, 3] < [1, 2, 4]
