There is also the shelve module.
It uses pickle to marshal a Python object, then stores it in a file
under a key.
Sample code from the module documentation:
import shelve
d = shelve.open(filename) # open -- file may get suffix added by
low-level library
d[key] = data # store data at key (overwrites old data if using an
existing key)
data = d[key] # retrieve a COPY of data at key (raise KeyError if no
such key)
del d[key] # delete data stored at key (raises KeyError if no such key)
flag = key in d # true if the key exists
klist = list(d.keys()) # a list of all existing keys (slow!)
