Question

ill thumb up do your best python3

CardDeck Class Represents the deck of cards Provided methods: _repr__(self); returns a legible representation of the deck of cards (simply outputs card values in order from the top of the deck to the bottom). Could be useful in debugging other parts of this assignment. o Parameters: • None o Returns: str shuffle(self): shuffles the deck of cards. All cards that have previously been drawn with the draw method are returned to the deck. o Parameters: None o Returns: • None Must implement the following methods: • draw(self): draws one card from the top of the deck and returns its value o Parameters: • None o Returns: • int the top of the deck, None if there is no top
