I need help with this answer in cengage, using Python.

Design, implement, and test a network application that maintains an online phone book. The data model for the phone book is saved in a file on the servers computer. Clients should be able to look up a persons phone number or add a name and number to the phone book. The server should handle multiple clients without delays. Unlike the doctor program, there should be just one phone book that all clients share. The server creates this object at start-up and passes it to the client handlers.

I need code for phonebook.py, phonebookclient.py, phonebookclienthandler.py, and phonebookserver.py.

This lab follows a client server model. In order for the client program to connect to the server the following steps must be taken: Enter python3 phonebookserver.py into the first Terminal. New terminal tab by clicking the '+' at the top of the terminal pane. Enter python3 phonebookclient.py into the second Terminal.
