please PM very sparingly.
It's OK to share with the forum.

As to your questions:

• delete person -- I'll add this for you, but may not get to it for a while.
       basically, to delete from a dictionary, you use del dictname[key]
  
• to prevent others from seeing results, you can add a password see: https://www.reddit.com/r/Python/comments...made_easy/
  

Thanks!

OK,  It now deletes, and I cleaned up a few things.
From here on, you're on your own.
Enjoy:

I haven't forgot about this, almost there.
Probably not today though.

[Larz60+]

still a few issues to be resolved... soon

[Larz60+]

Well, this has been quite an undertaking:
I said I would post last night, but there was too many loose ends.
There are still several methods here that don't work correctly and
it may take a while longer to complete.
Right now, about the only thing that seems to be solid is the add function
deletes are almost working, but not there yet.
I thought I'd post anyway so that you can start to get an idea of what's what.
As I stated before, the self.people dictionary will need to be replaced by a relational
database, suggest sqlite3. This will eliminate the json file. As is, so long as you have a reasonable
amount of memory it will hold quite a few people, before memory runs out.
