Python Forum

Hey guys, so I found this code on the web. I tried to run it and it works. The only thing is when I restart the program, all the supposed added/deleted were not save. I have heard that you should use File Function but I'm not sure how to edit/delete word from file. Any help will be appreciated.P.S This code does not belong to me

This could be written to be much easier and efficient to use, but save that for another day.
add two new items to the choice list:
5. Save to json file
6. Load from json file

Is this homework?

Thanks. Not really a homework. This is more like my for my own knowledge. I'm new to python.

In that case, here you go. As I stated before, this is poorly written, and could be redone:
