Python automated O & M learning day 1-day1, python-day1

I learned the homework I summarized on the first day of python automated O & M.

Knowledge used:
Json module for Data Conversion
Sys. exit is used to interrupt the loop exit program.
String formatting. format
Open and read dictionary and file
With open (file, "rw") as f:
F. redad/write
If: loop
Elif:
Else:
While: loop

Main purpose:
1. By default, the admin super-administrator user can achieve the following:

1). View blacklist users
2). Use admin to register a new user to the whitelist.
3). Remove the specified user from the blacklist

2. After the user enters the user name three times, the user will be locked for the last login.
3. the user name is entered correctly, but the password is entered incorrectly three times to automatically exit the program

4. Default whitelist User: hujianli password: admin #123
Huxiaojian password: admin #123
Xiaofei password: admin #123 enter the White List user to log on successfully. The welcome page is displayed. url information is provided.
5. Check the blacklist for each user input. An error is automatically reported in the blacklist. You need to unlock the blacklist.
6. automatically create three files under the same level Directory: whitelist directory \ blacklist directory \ admin hypermanaged directory === no database is replaced by a local file, and there is a database, information needs to be stored in the database
