Question

1. Write a class Volume that stores the volume for a stereo that has a value between 0 and 11. Usage of the class is listed below the problem descriptions. Throughout the class you must guarantee that:
   1. The numeric value of the Volume is set to a number between 0 and 11. Any attempt to set the value to greater than 11 will set it to 11 instead, any attempt to set a negative value will instead set it to 0.
   2. This applies to the following methods below: __init__, set, up, down

You must write the following methods:

3. __init__ - constructor.   Construct a Volume that is set to a given numeric value, or, if no number given, defaults the value to 0.   (Subject to 0 <= vol <=11 constraint above.)
4. __repr__ - converts Volume to a str for display, see runs below.
5. set – sets the volume to the specified argument (Subject to 0 <= vol <=11 constraint above.)
6. get – returns the numeric value of the Volume
7. up – given a numeric amount, increases the Volume by that amount. (Subject to 0 <= vol <=11 constraint above.)
8. down – given a numeric amount, decreases the Volume by that amount. (Subject to 0 <= vol <=11 constraint above.)
1. __eq__ - implements the operator ==.   Returns True if the two Volumes have the same value and False otherwise.

Answer 1

The question is missing the sample outputs, nevertheless the class has been fully implemented.

==============================================================================

class Volume():

    def __init__(self, vol=0):
        self.volume = vol
        if self.volume > 11:
            self.volume == 11
        if self.volume < 0:
            self.volume = 0

    def __repr__(self):
        return 'Stereo Volume: {}'.format(self.volume)

    def set(self, vol):
        self.volume = vol
        if self.volume > 11:
            self.volume == 11
        if self.volume < 0:
            self.volume = 0

    def get(self):
        return self.volume

    def up(self):
        self.volume += 1
        if self.volume > 11:
            self.volume == 11

    def down(self):
        self.volume -= 1
        if self.volume < 0:
            self.volume = 0

    def __eq__(self, other):
        if isinstance(other, Volume):
            return self.volume == other.volume
        else:
            return False
