Login and get codingIn this Bite we learn a bit of operator overloading. Finish the

`Thumbs`

class that returns an amount of thumbs up (👍) or thumbs down (👎) emojis based on the`int`

it is multiplied with.Override the corresponding dunder methods to make this work. No constructor method should be needed, the thumbs emojis to be used are defined in constants.

Best to see it in action using the REPL:

>>> from thumbs import Thumbs >>> th = Thumbs() >>> th * 1 '👍' >>> th * 2 '👍👍' >>> th * 3 '👍👍👍'Starting 4 it shortens by returns the emoji once, followed by the amount in parentheses:

>>> th * 4 '👍 (4x)' >>> th * 5 '👍 (5x)' >>> th * 6 '👍 (6x)' ...For negative numbers the emoji changes from thumbs up to thumbs down:

>>> th * -1 '👎' >>> th * -2 '👎👎' >>> th * -3 '👎👎👎'Again starting 4 it shows the number in parentheses (this was a real world use case actually):

>>> th * -4 '👎 (4x)' >>> th * -5 '👎 (5x)' >>> th * -6 '👎 (6x)' ...It should raise an exception if the number is 0:

>>> th * 0 Traceback (most recent call last): ... ValueError: Specify a numberAnd lastly it should work both ways:

>>> th * 1 '👍' >>> 1 * th '👍' >>> -3 * th '👎👎👎' >>> 7 * th '👍 (7x)' >>> -6 * th '👎 (6x)' >>> 0 * th ... ValueError: Specify a numberWe hope this shows you a bit of the power of operator overloading. If you want to learn more about Python's data model and
