A clаss definitiоn cаlled PrоpertyPоrtfolio is given below. Creаte code that will allow programs that use this class to determine how many properties are in this PropertyPortfolio by using the built-in 'len' feature. For example, coding "len(pp1)" for PropertyPorfolio object "pp1" will return how many properties are in the portfolio. class PropertyPortfolio ( ): def __init__(self, name, owner, address): self.__name = name self.__owner = owner self.__address = addres self.__properties = [ ] # Property object container def addProperty (self, p_obj): if type(p_obj) != Property: return False, 'can only add Property objects' self.__properties.append(p_obj) return True, 'added'
