Consider the following hierarchy of classes: class Person

(object): def_init_(self, name): self.name - name def

say(self, stuff): return self.name + says: def_str_(self):

return self.name + stuff class Lecturer(Person): def

lecture(self, stuff): return \'I believe that \' +

Person.say(self, stuff) class Professor(Lecturer): def

say(self, stuff): return self.name + \' says:\' +

self.lecture(stuff) class ArrogantProfessor(Professor) def

say(self, stuff): return \'It is obvious that\' + self.say(stuff)

As written, this code leads to an infinite loop when using

the class. Change the definition of so that the following

behavior is achieved: e = Person(\'eric\') lessthanorequalto

= Lecturer(\"eric\") pe = Professor(\'eric\') ae =

ArrogantProfessor(\"eric\") >>> e.say (\'the sky is blue\')

eric says: the sky is blue >>> le.say (\'the sky is blue\')

eric says: the sky is blue >>> le. lecture (\'the sky is blue\')

I believe that eric says: the sky is blue >>> pe.say (\'the

sky is blue\') eric says: I believe that eric says: the sky is

blue >>> pe. lecture (\'the sky is blue\') I believe that eric

says: the sky is blue >>> ae. say (\'the sky is blue\') eric

says: It is obvious that eric says: the sky is blue >>> ae.

lecture (\'the sky is blue\') It is obvious that eric says: the

sky is blue Paste ONLY your class in the box below. Do

not leave any debugging print statements. For this

question, you will not be able to see the test cases we run.

This problem will test your ability to come up with your own

test cases.
