Python __truediv__ magic method

"""
Magic method __truediv__ is called when a "/" is used on any object. 
Given example shows what I mean: print(some_object / other_object)
This may give error often, so that means given objects don't have __truediv__ method

    	self represents the object that is first and other is object after
    	"/" sign. What I say here is that I expect to have attribute "x" 
    	in both objects and I will try to divide them. This SHOULD BE
    	used for objects of the same type.
