The same way you'd view data in a dict : by iterating it.

Some of the database modules, including bsddb , don't have an __iter__ method, but they all have keys . So:

db = bsddb.hashopen("/home/neeraj/public_html/database/mydb.db","r")
for key in db.keys():
    print('{}: {}'.format(key, db[key]))
