Python学习第73天（shelve模块、习题练习）

　　翻了一下之前看的部分，是第16天学习的shelve模块，大致能容如下：

import shelve
# shelve模块，功能上类似于json和pickle，但是操作起来比较简单，是将传入数据转化为一个字典
# 但是在写入过程中我们看不到字典的存在，同时不能跨语言进行传输

# f = shelve.open(r'shelve_test1')    #此时会生成3个文件，但是你完全不用理会，因为你看不懂
# f['stu1_info1'] = {'name':'alex','age':18}   #将传入的字典{'name':'alex','age':18} 变成一个v值，
#                                              # 与我们写入的'stu1_info1'行程一个键值对，就是转换成为字典
# f['stu1_info2'] = {'name':'zhoujielun','age':28}
# f['shelve_test'] = {'k1':'v1'}
# f.close()

# print(f.get('stu1_info1')['name'])  #用f.get(k值)获取你要找到的字典，然后用字典内的k值得到对应的v
                                    #输出结果为：'alex'

　　上面就是关于shelve模块的部分，之前自己记得好像也不是很详细，关于怎么查询的明天还是得补上，今天勉强把剩下的学生界面和教师界面搞定，很是吃力啊，自己还是差的远，白天用得少，晚上又没咋联系，后期我将着重在每周日更新一次，然后平时就当是随堂笔记了。

　　上货吧：
