Suppose you are writing a Pet class to represent companion animals and its two children, DogandCat, in Python. What must you place in the blanks to ensure that objects instantiated from each child class can execute thespeak$()$method without errors?

class Pet$()$:

$de{f}_{{?}_{?}}ini{t}_{{?}_{?}}(self)$:

self.name $=\text{'}$

self.color $=\text{'}$

def speak$($self$)$:

raise NotImplementedError$("$Children of Pet must implement a speaking method."$)$

class Dog$($Pet$)$:

def$\_\_$init$\_\_($self$)$:

super$().()$

self.house$\_$trained $=$ True
