Data Persistence

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.
