Python binding for QDBM Database
Project description
This requires QDBM C Library (http://fallabs.com/qdbm/index.html)
Example code:
from qdbm import depot
db = depot.open(“test.db”, “n”) # depot.open(FILENAME, FLAG)
db[“apple”] = “red” # add data db[“lemon”] = “black” db[“orange”] = “orange”
db[“lemon”] = “yellow” # update data
print db[“lemon”] # get value that key is “lemon”
print db.get(“orange”, “unknown”) # get data with default value (returns orange)
print db.get(“melon”, “unknown”) # get data with default value (returns unknown)
print db.keys() # get list of keys (Python2), get iterator of keys (Python3)
print db.listkeys() # get list of keys (Python3)
- for k in db.iterkeys(): # get iterator of keys (Python2)
print k
- for k in db.keys(): # get iterator of keys (Python3)
print k
- for k, v in db.iteritems(): # get iterator of (key, value) (Python2)
print k, v
- for k, v in db.items(): # get iterator of (key, value) (Python3)
print k, v
- for v in db.itervalues(): # get iterator of values (Python2)
print v
- for v in db.values(): # get iterator of values (Python3)
print v
db.close() # close database object
- Flags:
r: Read Only
w: Read / Write
c: Read / Write (create if not exists)
n: Read / Write (always create new file)
