Python Multi-User Login

Demand:

• Can support multiple users login (prompt, through the list to save multiple account information)
• After the user 3 authentication failed, quit the program, start the program again when attempting to log on, or lock the status (hint: the user locked state must be stored in the file)

Flow chart:

Code:
