python持久化模块-shelve模块

python shelve模块

#导入模块
import shelve,datetime

d = shelve.open('shelve_test') #打开一个文件

info = {"age":25,"job":"it"}

name = ["abcd","rain","test"]
d["name"] = name   #持久化列表
d["info"] = info   #持久dict
d["date"] = datetime.datetime.now()
d.close()

d = shelve.open('shelve_test') #打开一个文件
print(d.get("name"))
print(d.get("info"))
print(d.get("date"))
d.close()

结果：
['abcd', 'rain', 'test']
{'age': 25, 'job': 'it'}
