Command-line user interfaces: • The user and computer interact with one another using the commands or through program code. • The command-line interface was popular before the introduction of the Graphical User Interface (GUI). • When a command is typed to interact with the computer, it is called as “command-line interface”. • The usage of commands in interacting with the computer requires the user to know basic syntax knowledge on how the command needs to be typed such that the computer will respond accordingly. • It will be little difficult for the beginner-level user to properly learn the syntax of the commands. • The commands are entered in the prompt screen for its execution.

Question

You will write a program that allows the user to keep track of college locations and details about each location. To begin you will create a College python class that keeps track of the csollege's unique id number, name, address, phone number, maximum students, and average tuition cost. Once you have built the College class, you will write a program that stores College objects in a dictionary while using the College's unique id number as the key. The program should display a menu in this order that lets the user: 1) Add a new College 2) Look up a College 4) Delete an existing College 5) Change an existing College's name, address, phone number, maximum guests, and average tuition cost. 6) Exit the program
