* The :mod:`xml.dom` and :mod:`xml.sax` packages provide robust support for
parsing this popular data interchange format. Likewise, the :mod:`csv` module
supports direct reads and writes in a common database format. Together, these
modules and packages greatly simplify data interchange between Python
applications and other tools.
* The :mod:`json` package provides robust support for parsing this
popular data interchange format. The :mod:`csv` module supports
direct reading and writing of files in Comma-Separated Value format,
commonly supported by databases and spreadsheets. XML processing is
supported by the :mod:`xml.etree.ElementTree`, :mod:`xml.dom` and
:mod:`xml.sax` packages. Together, these modules and packages
greatly simplify data interchange between Python applications and
other tools.
* The :mod:`sqlite3` module is a wrapper for the SQLite database
library, providing a persistent database that can be updated and
accessed using slightly nonstandard SQL syntax.
* Internationalization is supported by a number of modules including
:mod:`gettext`, :mod:`locale`, and the :mod:`codecs` package.
