shelve模块(* * *)
shelve模块比pickle模块简单,只有一个open函数,返回类似字典的对象,可读可写;key必须为字符串,而值可以是python所支持的数据类型
import shelve f = shelve.open(r'shelve.txt') # f['stu1_info']={'name':'alex','age':'18'} # f['stu2_info']={'name':'alvin','age':'20'} # f['school_info']={'website':'oldboyedu.com','city':'beijing'} # # # f.close() print(f.get('stu_info')['age'])
