[英]Need help on my first Blackjack Game (Text Version) in Python
我剛剛開始學習如何使用 python 編碼。 由於我是初學者，我正在嘗試制作僅基於文本的二十一點游戲。
二十一點中的一些規則也被簡化了：
我在運行代碼時遇到了一些錯誤：
注意：我可能遺漏了一些其他錯誤。
有沒有人願意給我一些關於修復上述錯誤的建議？
我的代碼貼在下面：

我看到了一些錯誤，包括游戲本身的邏輯。 例如，當玩家擊中時，你給庄家一張牌。 一旦發牌，庄家在玩家起立或爆牌之前不會抽牌。
您還想將程序的邏輯分解成更小的塊。 您可以將這些塊放入函數中。 下面的代碼應該讓你走上正軌。
from random import randint
# define a deal function - if you're new to functions,
# this code is just a definition. It doesn't run until
# you say 'deal()' in your program
def deal():
"""
Deal the cards. Since a hand is a group of cards, it is
easier to add them to a list, which holds a group of items.
"""
player_hand = [randint(1, 11), randint(1, 11)]
dealer_hand = [randint(1, 11), randint(1, 11)]
return player_hand, dealer_hand
# draw the next card
def draw_card():
return randint(1, 11)
# this function tells you how many aces are in your hand
# so you don't bust on a soft hand.
def count_aces(cards):
return sum([1 for card in cards if card ==11])
# take a card hand and return a boolean if the cards sum is greater than 21.
# notice we use the sum_hands function which we define below
def check_bust(cards):
return sum_hand(cards) > 21
# sum the hand given aces can be 1 or 11. Always take the maximum
# hand that doesn't bust
def sum_hand(cards):
total = sum(cards)
aces = count_aces(cards)
# return first hand less than 21
if total < 22:
return total
while aces > 0:
total = total - 10
aces = aces - 1
if total < 21:
return total

print(f'total is {total}')
print('')

player_cards, dealer_cards = deal()

while True:

display_hand(player_cards)
print('\nPlayer, hit or stand?')

# this is an f-string - you can print variables inside the {}
print(f'player {player_choose}s')
if player_choose == "stand":

if not player_wins:

display_hand(player_cards)
print('you lose')
return
# allow dealer to play
while True:

dealer_cards.append(draw_card())
continue

play_game()
您可以進一步優化它。 我在那里留下了一些重復的代碼，您可以根據需要將其重寫為函數。 最終的 play game 函數讀起來很流暢：
def play_game():
player_cards, dealer_cards = deal()
prompt()
player_plays(player_cards)
dealer_plays(dealer_cards)
result_prompt()
這只是一個粗略的例子，不是黃金標准或任何東西，只是為了顯示當你把它分解成更小的部分時，事情會變得更加清晰。 如果您對此有任何疑問，請告訴我。
謝謝，我已經進一步檢查了我的代碼。 請看一下。
