<p dir="ltr">Why not just create a base class to inherit from, since it's scattered everywhere. </p>

<br></div><div>Basically I have a bunch of classes like this scattered around different modules in my project:</div><div><br></div><div>class MyObject:</div><div> ABOVE = 1</div><div> BELOW = 2</div><div><br></div>

<div>
<br></div><div>If I have a bunch of different classes in different modules that each use their own ABOVE and BELOW, what's the best way to handle it? </div><div><br></div><div>Should I extract these constants to their own class, maybe in its own module?

<div><br></div><div>Should I keep the class constants within the classes, since ABOVE and BELOW might mean slightly different things in different classes?</div><div><br></div><div>Is there a better / more pythonic solution to this design issue?</div>
