Answer 1

HonFu. you were faster than me. I got the same idea with serializing objects with pickle.

Answer 2

There is a possibility to store dicts to a csv file (= comma separated values). Therefore use the csv module with:

import csv

This module has classes DictReader and DictWriter. I never used csv this way but I am sure you can find some code snippets to see how it should be.

For general use of reading and writing files see my tutorial:

Answer 3

The pickle module is easy to use when you don't need the data outside of Python.

You can also use json; codewise it's similarly easy.

You can also manually write the data to a txt file and read it from there, a few more lines of code then.

Answer 4

Just google pickle. It is really, really simple, you will definitely get it.
