Pickling - is the process whereby a python object hierarchy. It seems you want to save your class instances across sessions, and using pickle is a decent way to do this.

The following is an example of how you might write and read a pickle file. Note that if you keep appending pickle data to the file, you will need to continue reading from the file until you find what. Pickle is unsafe because it constructs arbitrary python objects by invoking arbitrary functions.

I have looked through the information that the python documentation for pickle gives, but i'm still a little confused. What would be some sample code that would write a new file and then use pickle. The pickle / cpickle pair received this treatment.
