#Class inheritance python code
What is the mistake that I am making and what are the test cases on which this code fails? (I am new to python and learned about classes some time ago. Return 'It is obvious that ' + Person.say(self, stuff)īut the checker gives only half marks for this solution. Python supports inheritance with an use of a minimum number of syntax and semantics. It comes handy in a lot of scenarios while designing or developing a complex software. The goal of inheritance is to reuse an already-built.
Return Person.say(self, ' It is obvious that ') + Person.say(self,stuff) Inheritance is one of the core topic of object oriented programming. But python classes arent only limited to this aspect, but they are also characterized by inheritance. My solution to this is: class ArrogantProfessor(Person): Pe.lecture('the sky is blue') #returns believe that eric says: the sky is blueĪe.say('the sky is blue') #returns eric says: It is obvious that eric says: the sky is blueĪe.lecture('the sky is blue') #returns It is obvious that eric says: the sky is blue class CustomError(MyProjectError): '''A custom exception class for MyProject.''' You can subclass custom exception classes as well to create a hierarchy. To create a specific exception, subclass the base exception class. Pe.say('the sky is blue') #returns eric says: I believe that eric says: the sky is blue Organizing the exception classes in a separate module (e.g. Le.lecture('the sky is blue') #returns believe that eric says: the sky is blue Python classes provide all the standard features of object-oriented programming, the class inheritance mechanism allows multiple base classes, a derived class. Python inheritance allows us to create a class that borrows all. The goal of inheritance is to reuse an already-built class to create a new class. Le.say('the sky is blue') #returns eric says: the sky is blue In python, we can borrow methods from one class to another class. Return 'It is obvious that ' + self.say(stuff)Īs written, this code leads to an infinite loop when using theĬhange the definition of ArrogantProfessor so that the followingĮ.say('the sky is blue') #returns eric says: the sky is blue Return self.name + ' says: ' + self.lecture(stuff)
