You Must create and use at least 5 meaningful functions.

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.

update (record, name, email)
elif flag == 4:
a function to change email (person)

Write a program that keeps names and email addresses in a dictionary as key-value pairs.
The program should display a menu that lets the user look up a person's email address, add a
new name and email address, change an existing email address, and delete an existing name and
email address. The program should save the data stored in a dictionary to a file when the user
exits the program. Each time the program starts, it should retrieve the data from the file and store
it in a dictionary.
record[name] = email
print ("Information updated")
if name in record:
del record[name]
print ("Information deleted")
You Must create and use at least 5 meaningful functions.
else:
A function to display a menu
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.

x = line. split(" ")

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.
