So far, we can create a new Clock object, but we can't do anything with it$.$ Next, we need to define additional operations that can be performed on our Clock objects. We added three methods that can be used to extract the individual components of the data contained in the object, and three methods to adjust or shift the seconds stored in the objects.

class Clock:

def $\_\_$init$\_\_($self$,$ hr$,$ min, sec$)$:

self.hours $=$ hr

self.minutes $=$ min

self.seconds $=$ sec

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

return self.hours

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

return self.minutes

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

return self.seconds

def shift$\_$seconds$($self$,$ sec$)$:

if sec $>0$ and self.seconds $+$ sec $<60$:

self.seconds $+=$ sec

return self.seconds

return 'Unsuccessful operation'

We can use the new methods to extract and print the values of one of the objects we just created:

$>>>$ hrsA $=$ clockA.get$\_$hours$()$

$>>>$ minA $=$ clockA.get$\_$minutes$()$

$>>>$ clockB.shift$\_$seconds$(10)$

$>>>$ display $=$ f'Clock time is $\{$hrsA$\}$ hour$($s$)$ and $\{$minA$\}$ minute$($s$)\text{'}$

$>>>$ display

'Clock time is $12$ hour$($s$)$ and $59$ minute$($s$)\text{'}$

Which of the following retrieves the seconds from clockB?

Group of answer choices

clockB.get$\_$seconds$()$

clockA.get$\_$seconds$($clockB$)$

clockB.get$\_$seconds$($self$)$

Clock.get$\_$seconds$()$
