Python

This assignment involves the use of a dictionary, functions, and exception handling. Write a program that keeps names and email addresses in a dictionary called people as key-value pairs. The program should initialize the dictionary with three people/email addresses. Then, the program should display a menu as follows and loop until 5 is selected: Create functions and use arguments/parameters as shown in the hierarchy chart/data flow diagram below. Create each of the functions and create the main program which calls the functions. Use try/except blocks to handle the KeyError exception. Use test data as follows: o Enter a number that is not a valid selection (1-5) if invalid, give an error message o Add several names/email addresses If the name already exists, give a message and dont attempt to add it to dictionary o Look up an existing name and display associated email address Look up a name that does not exist in the dictionary and handle the exception o Change the email address associated with an existing name If the name doesnt exist, give a message and dont attempt to change it o Delete an existing name/email pair If the name doesnt exist, handle the exception Make sure to include header and step comments in your program.
