| 4 | The modules described in this chapter support storing Python data in a |
| 5 | persistent form on disk. The \module{pickle} and \module{marshal} |
| 6 | modules can turn many Python data types into a stream of bytes and |
| 7 | then recreate the objects from the bytes. The various DBM-related |
| 8 | modules support a family of hash-based file formats that store a |
| 9 | mapping of strings to other strings. The \module{bsddb} module also |
| 10 | provides such disk-based string-to-string mappings based on hashing, |
| 11 | and also supports B-Tree and record-based formats. |
