Python中的anydbm模版和shelve模版使用指南

#coding=utf-8
 
import anydbm
 
def CreateData():
  try:
    db = anydbm.open('db.dat', 'c')
    
# key与value必须是字符串
    
# db['int'] = 1
    
# db['float'] = 2.3
    db['string'] = "I like python."
    db['key'] = 'value'
  finally:
    db.close()
 
def LoadData():
  db = anydbm.open('db.dat', 'r')
  for item in db.items():
    print item
  db.close()
 
if __name__ == '__main__':
  CreateData()
  LoadData()

import shelve
 
def CreateData():
  try:
    db = shelve.open('db.dat', 'c')
    
# key与value必须是字符串
    db['int'] = 1
    db['float'] = 2.3
    db['string'] = "I like python."
    db['key'] = 'value'
  finally:
    db.close()
 
def LoadData():
  db = shelve.open('db.dat', 'r')
  for item in db.items():
    print item
  db.close()
 
if __name__ == '__main__':
  CreateData()
  LoadData()
