The modules described in this chapter support storing Python data in a
|
||
|
|
persistent form on disk. The \module{pickle} and \module{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 \module{bsddb} module also
|
||
|
|
provides such disk-based string-to-string mappings based on hashing,
|
||
|
|
and also supports B-Tree and record-based formats.
