# 使用配置文件
# why ：给程序提供一些默认的或个性化的全局参数
# what： 分块kv存储，默认形式有 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为项目51备忘录扩展功能
#针对上次作业的MemoAdmin类
# 1，添加注册和登陆功能，用户密码使用dict保存为：users.pkl
# 2. 添加配置文件，为备忘录数据指定路径，类型和文件名
# 比如coop，则数据文件可以为coop.pkl或者coop.db
# 3.注册时，相应数据文件根据用户名在配置文件保存为新的section，
# 如coop,则有新的section 叫做[coop]
# 4 .启动程序先提示登陆每次登陆时候，先根据配置文件读取用户信息，找不到，提示注册
