You Must create and use at least 5 meaningful functions.

A function to look up a person's email address
A function to add a new name and email address
A function to change an email address
A function to delete a name and email address.

Your program should check user input; for example, if the user wants to delete a name that does
not exist in the dictionary, you should print something like: the name is not in the database. A
sample one run is shown below.
