You don't mention what type of data you want to store? Is it a
single string? Multiple strings? Complex nested data?
And how do you want to access it?
Python provides you any number of options:
- you can use standard Python file objects to read/write content
in a file format of your own definition
- you can use the ConfigParser module to read/write an old-school
.INI style file (which can also be edited in a text editor, but
doesn't have to be)
- you can use the "anydbm" module to store key/value pairs of
strings with an internal user-interface much like a dictionary
- you can use the "pickle" module to persist Python objects into
files
- you can use the "shelve" module to combine the "pickle"
persistence with the DBM layer
- you can use the built-in (as of Python2.5) "sqlite3" module for
a single-file database with full SQL capabilities without the
need to install a SQL server (MySQL, PostgreSQL, MS SQL Server, etc)
- you can persist to cloud storage or to your own web-server
using the urllib/urllib2 modules
But without knowing what you want to store or how you want to
access it, it's hard to offer more concrete advice.
