What is the best practice to code an Interrupt in a python Class?

[pabloarthurrodger]

This is not an Issue, I just want to request an example of an Interrupt in a Class.

I do have a Interrupt trigger to a Callback function on a Class of a Movement Sensor

When I am importing the movement sensor Class in my code (since there are movement around) immediately start triggering the Callback function that gives an error because it does not have a "self" instance. (I am just importing the Class).

My question is there is a workaround? What is the best practice to code an Interrupt in a python Class?

Thanks in Advance,

Pablo.
