# 使用配置文件
# why :給程序提供一些默認的或個性化的全局參數
# what: 分塊kv存儲,默認形式有 ini,conf, cfg
# how : configparse, http://devdocs.io/python~3.6/library/configparser

#Signature: config.read(filenames, encoding=None)
Docstring:
Read and parse a filename or a list of filenames.
Files that cannot be opened are silently ignored; this is
designed so that you can specify a list of potential
configuration file locations (e.g. current directory, user's
home directory, systemwide directory), and all existing
configuration files in the list will be read. A single
filename may also be given.

# 使用configadmin爲項目51備忘錄擴展共鞥
#針對上次作業的MemoAdmin類
# 1,添加註冊和登陸功能,用戶密碼使用dict保存爲:users.pkl
# 2. 添加配置文件,爲備忘錄數據指定路徑,類型和文件名
# 比如coop,則數據文件可以爲coop.pkl或者coop.db
# 3.註冊時,相應數據文件根據用戶名在配置文件保存爲新的section,
# 如coop,則有新的section 叫做[coop]
# 4 .啓動程序先提示登陸每次登陸時候,先根據配置文件讀取用戶信息,找不到,提示註冊
