title: How to implement a settings file in a Python program
body: <p>A "settings file" would be a file where things like "background color", "speed of execution", "number of x's" are defined. Currently, I implemented it as a single <code>setting.py</code> file, which I import in the beginning. Someone told me I should make it a <code>settings.ini</code> file instead, but I don't see why! Care to clarify, what is the optimal option?</p>
