$ pydoc shelve

To summarize the interface (key is a string, data is an arbitrary
object):
...
d[key] = data # store data at key (overwrites old data if
# using an existing key)
data = d[key] # retrieve a COPY of the data at key (raise
# KeyError if no such key) -- NOTE that this
# access returns a *copy* of the entry!
del d[key] # delete data stored at key (raises KeyError
# if no such key)
...
Seems pretty straightforward. :-) Are you having some sort
of problem with "del"?
