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.config.add_section(‘fang‘) # 向config中增加section：config.add_section()config.set(‘fang‘, ‘db_name‘, ‘ccoop.pkl‘) #设置‘fang’的子集with open(config_path, ‘w‘) as f:

# 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
