Using import sys : Create a python program username.py, that has a function that takes as arguments a
first and last name and creates a username. The username will be the first letter
of the first name in lowercase, the last 7 of the last name in lowercase, and the
total number of characters in the first and last names. For example, Eastern
University would be eversity17.
● The program should print "Your username is x" where x is the username.
