Python賭博骰子游戲？

Question

我是學習 Python 的新手，並且正在努力創建這個擲骰子賭博游戲。 我已經在它上面度過了愉快的一周，但仍然對無法使其正常/完全工作感到沮喪。 基本上我很難讓它正確打印並繼續詢問用戶的擲骰子猜測（2到12之間）。 我提前感謝任何人的幫助和建議！

Answer 1

您的total_bank()方法可能會導致問題。

def total_bank():
    bank = 500
    while bank > 0:
        print("You have ${bank} in your bank.")
        bet = int(input("Enter your bet: "))

當你調用這個函數時，它會告訴你你的銀行有多少錢，一旦你輸入你的賭注，它會再次這樣做，因為銀行仍然 >0。 所以，你只會被困在這個無限循環中。

此外，在這種情況下，您將需要大量global關鍵字。 雖然不建議使用它，但我認為在這種情況下很好。 您實際上並未更改銀行金額 - 該bank變量是一個局部變量，這意味着您無法在total_bank函數之外訪問它。 每次給bank打電話都得還錢。

所以，代碼應該是

def total_bank():
    bank = 500
    print(f"You have ${bank} in your bank.")
# you forgot to make in a f-string
    bet = int(input("Enter your bet: "))
    bank-=bet
    return bank

但是，它可能不適合您的目的。 例如，您可以查看限制賭注等。我只是在簡化它。

像這樣的東西可能是你真正想要的，但我不確定。

def total_bank():
    bank = 500
    print(f"You have ${bank} in your bank.")
# you forgot to make in a f-string
    while bet <= 500: #whatever number is fine
        bet = int(input("Enter your bet: "))
    return bank, bet

bank, bet = total_bank()

希望這能回答你的問題！

Answer 2

'F' 字符串

F 字符串將花括號 {} 中的任何內容替換為表達式的值，例如函數的返回值或任何變量/值：

print(f"abc{1+2}") # output: abc3

在您的prog_info函數中，您的打印語句實際上並不需要 F-Strings 但是，諸如此類的行需要使用 F-Strings，因為您需要替換以下值：

print("You have ${bank} in your bank.")
print('Die Roll #1 was {roll}')

游戲循環

如果不滿足任何條件，您可以使用 if 語句在里面實現 while True 循環以退出

bank = 500 # Initial Amount    

while True:
    # Ask user for their bet/guess
    print(f'You have ${bank} in your account')
    print(f'Choose a number between 2-12')
    guess = get_guess()
    if guess == 0:
        break  # This stops the loop
    
     # Roll Dice, Add/Subtract from their bank account, etc.
    
     # Check if their bank account is above 0 after potentially subtracting from their account
     if bank <= 0:
         break
else:
     print("Thanks for playing")  # Game has ended

Answer 3

如果對total_bank函數和主循環進行一些更改，就會得到想要的結果。

試試這個代碼：

import random

def rollDice():
    die1 = random.randint(1,6)
    die2 = random.randint(1,6)
    x = int(die1 + die2)
    print('Roll', x)
    return x

def prog_info():
    print("My Dice Game .v02")
    print("You have three rolls of the dice to match a number you select.")
    print("Good Luck!!")
    print("---------------------------------------------------------------")
    print(f'You will win 2 times your wager if you guess on the 1st roll.')
    print(f'You will win 1 1/2 times your wager if you guess on the 2nd roll.')
    print(f'You can win your wager if you guess on the 3rd roll.')
    print("---------------------------------------------------------------")

def total_bank(bank):
    bet = 0
    while bet <= 0 or bet > min([500,bank]):
        print(f"You have ${bank} in your bank.")
        a = input("Enter your bet (or Q to quit): ")
        if a == 'q': exit()
        bet = int(a)
    return bank,bet

def get_guess():
    guess = 0
    while (guess < 2 or guess > 12):
        try:
            guess = int(input("Choose a number between 2 and 12: "))
        except ValueError:
            guess = 0
        return guess

prog_info()
bank = 500

while True:
    bank,bet = total_bank(bank)
    guess = get_guess()

    if guess == rollDice():
        bank += bet
    elif guess == rollDice():
        bank += bet * .5
    elif guess == rollDice():
        bank = bank
    else:
        bank = bank - bet

    print(f'You have ${bank} in your bank.')
    print(f'Thanks for playing!\n')
