Question

What is the preferred/ usual way of storing data that is entered by the user when running a Python script, if I need the data again the next time the script runs?

Answer 1

For 100 lines, plain text is fine with either the standard ConfigParser or csv modules.

Assuming your data structure is simple, text affords opportunities (e.g. grep, vi, notepad) that more complex formats preclude.
