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