Updated documentation. Merged revisions 63042 via svnmerge from svn+ssh://pythondev@svn.python.org/python/trunk ........ r63042 | alexandre.vassalotti | 2008-05-11 04:25:28 -0400 (Sun, 11 May 2008) | 5 lines Added module stub for copy_reg renaming in 3.0. Renamed copy_reg to copyreg in the standard library, to avoid spurious warnings and ease later merging to py3k branch. Public documentation remains intact. ........

The modules described in this chapter support storing Python data in a
|
|
persistent form on disk. The :mod:`pickle` and :mod:`marshal` modules can turn
|
|
many Python data types into a stream of bytes and then recreate the objects from
|
|
the bytes. The various DBM-related modules support a family of hash-based file
|
|
formats that store a mapping of strings to other strings. The :mod:`bsddb`
|
|
module also provides such disk-based string-to-string mappings based on hashing,
|
|
and also supports B-Tree and record-based formats.
