For the subclass Contractor of the base class Person example provided in the tutorial, what if we need to keep track of the project for each contractor? What code segment could be used to properly initialize, and add methods to set and get this value?

a$.)$

class Contractor$($Person$)$:

def $\_\_$init$\_\_($self$,$fname,lname$,$title,wage,contractorid$)$:

super$().\_\_$init$\_\_($fname$,$lname$,$title$)$

self.contractorid $=$ contractorid

self.hourlywage $=$ wage

self.project $=$ project

def get$\_$project$($self$)$:

return self.project

def set$\_$project$($self$,$ project$)$:

self.project $=$ project

b$.)$

class Contractor$($Person$)$:

def $\_\_$init$\_\_($self$,$fname,lname$,$title,wage,contractorid,project$)$:

super$().\_\_$init$\_\_($fname$,$lname$,$title$)$

self.contractorid $=$ contractorid

self.hourlywage $=$ wage

self.project $=$ project

def get$\_$project$($self$)$:

return self.project

def set$\_$project$($self$,$ project$)$:

self.project $=$ project
