Re: [Tutor] need advice about a dictionary ({})

So I've done quite a bit more work. With phone_book.py the user can not only access phone numbers by the person's initials, but can add items to the data file. I've also solved the problem of adding a person who's initials have already been used in a key. I've pasted phone_book_for_pasting.py at <

Re: [Tutor] need advice about a dictionary ({})

Thanks so much, Jack. You've given me much to chew on. I began phone_book.py without much need for it -- I already had an RTF file with 786 lines that I "grepped" using a script I wrote with Tutor help long ago. I used an RTF file instead of a text file so that any URLs in it would be live. But I
