Craps游戏投注模块输入处理异常及功能完善技术咨询

问题描述 #

开发带虚拟钱包的Craps骰子游戏时，投注环节存在输入校验逻辑混乱、钱包余额未正确更新、缺少游戏核心流程（骰子投掷、输赢结算）及结束条件判断的问题，需实现以下功能：

• 校验用户投注输入是否为数字，非法输入需重新输入
• 验证投注金额是否在钱包余额范围内，超出则要求重新输入
• 合法投注后提供"roll dice"选项启动游戏
• 获胜时获得双倍投注金额，失败扣除投注金额，实时更新钱包余额
• 当余额≥1000或<0时，游戏自动结束

else:
    print("Welcome")
    print("Hold on... I'm missing something,")

# those who need instructions can ask for it,
# others can start the game directly.

    print('''1. the player will roll two six sided dice. the sum of the two dice is the player's number for the round.

3. the fated player continues to roll the two dice again until one of two things occur: either they roll the 'point' again, causing them to win the game; or they roll a 7, causing them to be doomed to the eternals.''')

关键改进说明 #

• 钱包类型修正：将money从字符串改为整数，解决数值比较错误问题
• 投注输入校验：嵌套循环确保用户输入正整数且不超过余额，非法输入时持续提示重新输入
• 骰子投掷触发：新增"roll dice"输入校验，确保用户明确触发游戏环节
• 核心游戏逻辑实现：完成Craps规则的骰子投掷、输赢判断（第一轮直接胜负/点数循环）
• 余额结算与结束条件：实时更新钱包余额，当余额≥1000或<0时自动终止游戏并显示对应结局
