Now you've saved the data in a different file.  How does the next run of=20
the program find it?=20


What user?  In what environment can a user enter function calls into=20
your code?=20
-The user will call the function out from IDLE

Why is the command invalid?=20
-Because the user need to type out a name after the "f"

That's not the way the message is worded in the code=20
- because if user type in " a John Cleese, Cheese Shop, 5552233, 5 May"
it mean it would takes four arguments (comma separated) with information=20
about a person and adds that person to my "friends.csv". An error message i=
s printed if that person is already a friend. Because the name "John Cleese=
" is already in my friends.csv that why it will prompt out "John Cleese is =
already a friend"

In this function and in save_friends, there is no return value, so not=20
clear what you mean by  'result'=20

e ends the interaction and, if the friends information has been
updated, the information is saved to the friends.csv , i think i used the w=
rong function for this.

The question I'm told to work on:
interact() is the top-level function that de=0Cnes the text-base user inter=
face
as described in the introduction.

Here is an example of what is expected from your program. The input is
everything after Command: on a line (and the initial friends.csv). Every-
thing else is output. Your output should be exactly the same as below for
the given input.

interact()=20
Friends File: friends.csv=20
Command: f John Cleese=20
John Cleese: Ministry of Silly Walks, 5555421, 27 October=20
Command: f Michael Palin=20
Unknown friend Michael Palin=20
Command: f=20
Invalid Command: f=20
Command: a Michael Palin=20
Invalid Command: a Michael Palin=20
Command: a John Cleese, Cheese Shop, 5552233, 5 May=20
John Cleese is already a friend=20
Command: a Michael Palin, Cheese Shop, 5552233, 5 May=20
Command: f Michael Palin=20
Michael Palin: Cheese Shop, 5552233, 5 May=20
Command: e=20
Saving changes...=20
