python - 当 balance 等于 bet 时程序不执行 elif 语句

Question

每当我运行程序并且下注值等于余额时，它不会显示我设置为显示的 else 语句，而是会关闭程序并输出应该稍后输出的其他信息。

以下是下注不等于余额以及彼此相等时发生的情况的示例：

Welcome to the Dice Game!
How much money would you like to play with?:100
How much would you like to bet?:50
What number would you like to bet on?:12
Now rolling....
Sorry, but you rolled a 7.
You now have $50.
Would you like to play again (N/Y)?yes
How much would you like to bet?:50
What number would you like to bet on?:12
Now rolling....
Would you like to play again (N/Y)?

Answer 1

就像人们在评论中所说的那样。你遇到的问题是这个

Balance -= Bet
...
while Balance >= Bet:
    # do rest

因此，当您Bet等于时，Balance它将减去它并且条件不再有效。你想要的是在while循环内移动减法

...
while Balance >= Bet:
    Balance -= Bet
    # do rest

我注意到的另一个问题是您有两个 while 循环，而第二个循环将始终运行一次。所以甚至没有理由拥有它，用if语句替换它并删除此循环break内部的语句内部是有意义的。ifwhile

编辑：在评论中回答作者的问题。你替换 make second whilean if：

if Balance >= Bet:
    Balance -= Bet
    if (Betnumber == 2) and (Numberrolled == 2):
        Winning1 = Bet * 36
        print(f"Congratulations! You rolled a 2 and won ${Winning1}!")
        Balance += Winning1
        print(f"You now have ${Balance}.")
    elif (Betnumber == 3) and (Numberrolled == 3):
        Winning2 = Bet * 18
        print(f"Congratulations! You rolled a 3 and won ${Winning2}!")
        Balance += Winning2
        print(f"You now have ${Balance}.")
    elif (Betnumber == 4) and (Numberrolled == 4):

        Balance += Winning3
        print(f"You now have ${Balance}.")
    elif (Betnumber == 5) and (Numberrolled == 5):
