Using Python programmingYour company needs a way to keep track of vendor email addresses. 

Create a program that keeps vendor names and email addresses in a dictionary as key-value pairs. The key should be vendor name. The program should display a menu that lets the user chose an action . . . - look up a vendor's email address, - add a new vendor and email address, - delete an existing vendor and email address or - change an existing email address. Your program should allow the user to process any number of transactions; some mechanism for the user to indicate they are done should be programmed.  When the user is done, but before ending the program, print all vendors and email addresses in a neatly formatted list.  

Comment your source code and describe your code to someone who may be viewing it for the first time.
