-The :mod:`string` module contains a number of useful constants and classes
-for string formatting. In addition, Python's built-in string classes
-support the sequence type methods described in the :ref:`typesseq`
-section, and also the string-specific methods described in the
-:ref:`string-methods` section. To output formatted strings, see the
-:ref:`string-formatting` section. Also, see the :mod:`re` module for
-string functions based on regular expressions.
