The dbm Module

(Optional) The dbm module provides an interface to the dbm database handler (available on many Unix platforms). This is shown in Example 10-6.

Example 10-6. Using the dbm Module

File: dbm-example-1.py

import dbm

db = dbm.open("dbm", "c")
db["first"] = "bruce"
db["second"] = "bruce"
db["third"] = "bruce"
db["fourth"] = "bruce"
db["fifth"] = "michael"
db["fifth"] = "bruce" # overwrite
db.close()

db = dbm.open("dbm", "r")
for key in db.keys():
 print repr(key), repr(db[key])

'first' 'bruce'
'second' 'bruce'
'fourth' 'bruce'
'third' 'bruce'
