Steps:
Import Required Modules:
To begin, we need to import the socket module, which provides the necessary functions for working with network-related tasks.
Get Hostname from the User:
Ask the user to input the hostname for which they want to retrieve the IP address.
Retrieve IP Address:
Use the gethostbyname() function from the socket module to obtain the IP address corresponding to the provided hostname.
The gethostbyname() function may raise a socket.gaierror if the hostname is not valid. We handle this exception to provide a meaningful error message.
