Implement a function that creates account details of new users: For this task, your script should create a user account for a user, given the users real name (First and Last names), the username to be assigned to the user, and a default password for the user. The real name and username for each user is provided in the file newusers.csv(below). Use an in-built function in python to generate the password for each user. This task should be implemented using a user-defined function. Your function should handle exceptions when the username that is being added already exists in the system. Please code in Python.

BELOW IS THE FILE newusers.crv:
