Question

Hi! I've asked this multiple times but the code given by the expert is wrong. Below is the supposedly correct output, and my current one. Please fix, thank you!

### Template

import random

class Card:

def __init__(self, value, suite):

self.value = value

self.suite = suite

def __str__(self):

return f"{self.value} of {self.suite}"

def __eq__(self, other):

"""Check if two cards are the same"""

# -- YOUR CODE HERE --

return (self.value == other.value and self.suite == other.suite)

class CardSet:

def __init__(self):

self.cards = []

def view(self):

for card in self.cards:

print(card)

def add_cards(self, cards):

"""Add cards to your set"""

# -- YOUR CODE HERE --

for card in cards:

self.cards.append(card)

class Deck(CardSet):

def __init__(self):

"""Initialize the 52-card set. Start from 1-11, then Jack, Queen, King, then by suite: clubs, spades, hearts, diamonds"""

cards = []

# -- YOUR CODE HERE --

for suite in ("clubs", "spades", "hearts", "diamonds"):

for value in ("1", "2", "3", "4", "5", "6", "7", "8", "9", "10", "Jack", "Queen", "King"):

card = Card(value, suite)

cards.append(card)

self.cards = cards

def count_cards(self):

""""Count the number of cards in a deck"""

# -- YOUR CODE HERE --

return len(self.cards)

def shuffle(self, seed=None):

"""Shuffle your deck using a random seed"""

random.seed(seed)

# -- YOUR CODE HERE --

random.shuffle(self.cards)

def peek(self, number=5):

"""Show the top n cards of the stack. This is analogous to getting the last n cards then reversing it."""

# -- YOUR CODE HERE --

cnt = 0

if number > len(self.cards):

else:

cnt = number

for i in range(-5, -5+cnt):

def draw(self, cardset, number=5):

# -- YOUR CODE HERE --

if number > len(self.cards):

else:

cnt = number

for i in range(-5, -5+cnt):

cards.append(self.cards[i])

self.cards.pop()

cards.reverse()

cardset.add_cards(cards)

def add_cards(self):

pass

if __name__ == "__main__":

seed, hand, peek = input().split(",")

myDeck = Deck()

handA = CardSet()

handB = CardSet()

myDeck.shuffle(int(seed))

for x in range(1,3):

print(f"\nRound {x}:")

myDeck.draw(handA, int(hand))

myDeck.draw(handB, int(hand))

print("Hand A: ")

handA.view()

print("Hand B: ")

handB.view()

myDeck.count_cards()

if(x == 1):

print(f"\n{peek} Cards at the top: ")

myDeck.peek(int(peek))
