examplemultidimensional vector class to demonstrate the use of operator overloading via special methodswe provide an implementation of vector classrepresenting the coordinates of vector in multidimensional space for examplein three-dimensional spacewe might wish to represent vector with coordinates - although it might be tempting to directly use python list to represent those coordinatesa list does not provide an appropriate abstraction for geometric vector in particularif using liststhe expression [ - [ results in the list [ - when working with vectorsif - and one would expect the expressionu vto return three-dimensional vector with coordinates we therefore define vector classin code fragment that provides better abstraction for the notion of geometric vector internallyour vector relies upon an instance of listnamed coordsas its storage mechanism by keeping the internal list encapsulatedwe can enforce the desired public interface for instances of our class demonstration of supported behaviors includes the followingv vector( [ [- print( [ ] = + print(utotal for entry in vtotal +entry construct five-dimensional (based on use of setitem (also via setitem print (via getitem (via add print implicit iteration via len and getitem we implement many of the behaviors by trivially invoking similar behavior on the underlying list of coordinates howeverour implementation of add is customized assuming the two operands are vectors with the same lengththis method creates new vector and sets the coordinates of the new vector to be equal to the respective sum of the operandselements it is interesting to note that the class definitionas given in code fragment automatically supports the syntax [ - ]resulting in new vector that is the element-by-element "sumof the first vector and the list instance this is result of python' polymorphism literally"polymorphismmeans "many forms although it is tempting to think of the other parameter of our add method as another vector instancewe never declared it as such within the bodythe only behaviors we rely on for parameter other is that it supports len(otherand access to other[jthereforeour code executes when the right-hand operand is list of numbers (with matching length
