Each piece of information (i.e. name, street, etc.) will be stored in the file on separate lines. There will be a blank line at the end of the contact information of each person. This program is menu driven. When the program is initiated, a function opens the file phone xt reads the data from the file creates a Contactlnfo object and stores that object as the value in a dictionary where the name of the person is the key. The menu choices are: 1. add a person 2. delete a person 3. search for a person 4. update the information of a person 5. save and quit the program The opening screen for the phone book will appear as shown below: Phone Book 1. Add a Perso 2 Delete a Person 3. Search for a Peraon 4.Update Information on a Person Quit Enter your selection: The user wll make a menu selection by typing a number between 1 and 5. If the user selects a number other than a number in that range then you will state that it is an invalid selection and ask the user to select again. You will keep prompting until the user either makes a valid selection or quits. Each valid selection will be handled by a separate function. After your program has handled menu items 1 through 4, the same menu should reappear for additional requests by the user. The handling of each menu item is explained in detail below. When the user selects menu item 5, the appropriate function is called and then the program prints a message thanking the user. Thank you for using the phone book
