The returned object is a dbhash, gdbm, dbm or dumbdbm object,
|
|||
|
|
dependent on the type of database being opened (determined by whichdb
|
|||
|
|
module) in the case of an existing dbm. If the dbm does not exist and
|
|||
|
|
the create or new flag ('c' or 'n') was specified, the dbm type will
|
|||
|
|
be determined by the availability of the modules (tested in the above
|
|||
|
|
order).
|
|||
|
|
|
|||
|
|
It has the following interface (key and data are strings):
|
|||
|
|
|
|||
|
|
d[key] = data # store data at key (may override data at
|
|||
|
|
# existing key)
|
|||
|
|
data = d[key] # retrieve 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
|
|||
|
|
list = d.keys() # return a list of all existing keys (slow!)
|
|||
|
|
|
|||
|
|
Future versions may change the order in which implementations are
|
|||
|
|
tested for existence, and add interfaces to other dbm-like
|
|||
|
|
implementations.
