Where is the realization of interface located in python module?

Question

Here is the code to which I can't find the realization in a .py file:

def distance(self):
    """Measures the relative distance between the sensor and an object using
    infrared light.

    Returns:
        :ref:`relativedistance`: Relative distance ranging from 0 (closest)
        to 100 (farthest).

    """
    pass

contents of module

Answer 1

The code you've shown is a class method that does nothing, so I assume you think there is a class definition somewhere else in the module that subclasses it and overrides that method? You'll just have to search for it.

If the class definition that contains the function you show is called BaseClass then you're looking for something like

class MyClass(BaseClass):
    
    # some other stuff here
    
    def distance(self):
        # this is what you are looking for

Obviously MyClass is an example name, it might be called anything.
