Hi all, I would require advise on this question for function call interact:
the desire outcome:
interact()
Friends File: friends.csv
Command: f John Cleese
John Cleese: Ministry of Silly Walks, 421, 27 October
Command: f Michael Palin
Unknown friend Michael Palin
Command: f
Invalid Command: f
Hi Dave,
Sorry for my unclear question.
I didn't use the d = load_friends('friends.csv') now because I'm going use it
for other function later on, I should have remove it first to avoid confusion.
This is the code for load_friends , add_info ,display_friends, save_friends
function:
def load_
Now you've saved the data in a different file. How does the next run of
the program find it?
What user? In what environment can a user enter function calls into
your code?
-The user will call the function out from IDLE
Why is the command invalid?
-Because the user need to type out a name
cient. I would expect there is something like:
name.is_key(name_key)
I appreciate your help!

This can help to pinpoint where the memory leak is occurring.

When any of them need any database access, whether for reading or for

Therefore, as I see it, if you are developing a project using scenario 1
