The Python script accomplishes the following tasks:
* It imports the required libraries for HTTP, base64, SSL, and sys modules.
* It takes the host, user, and password information from the command line arguments and assigns them to variables.
* It creates an HTTPS connection object using the host and port 9060, and specifies the SSL protocol as TLSv1_2.
* It encodes the user and password information in base64 format for basic HTTP authentication.
* It sets the headers for the HTTP request, including the accept, authorization, and cache-control fields.
* It sends a GET request to the Cisco ISE server to retrieve information from the
"/ers/config/internaluser/" endpoint, which returns the list of internal users configured on Cisco ISE.
* It reads the response from the server and prints the status, headers, and body in a human-readable format.
The script authenticates to the Cisco ISE server using the username of ersad and the password of Password1, and retrieves the internal user information from the server.
