CodePudding user response：

You seem to use pos in the main method if one.isOver(pos): but you're not defining pos beforehand. Where are you getting the value of pos? It should be assigned before or calculated with the class values.

CodePudding user response：

You're using the pos variable in your code, but it needs to be defined and have a value first. So, for example, you would have to write pos = (0, 0) (for example after defining one) if your coordinates are 0 and 0.
