I need to add these steps

$5.$ Security and Error Handling $(5\%)$ Error Logging: Centralized error logging with timestamps. $$ Security Validation and Input Sanitization: Check for valid inputs and safe handling of sensitive information. Example Usage Command: python$3$ sys$\_$admin.py user $--$create$-$user "invalid username" Expected Output: $[$ERROR$]$ Invalid username format. Usernames should not contain spaces. $[$INFO$]$ Error logged to error$\_$log$.$log$.$

$6.$ Code Documentation and ReadMe $(5\%)$ Code Comments: Comment each function and describe parameters and functionality. README File: Overview, setup, usage instructions, and any dependencies
