Python新手开发僵尸末日游戏遇验证码匹配正确仍重复验证问题

核心错误原因 #

• 类型不匹配：你生成的passcode是5位字符串类型，用户输入被你用int()强制转成了整数，不同类型的变量比较结果永远为False，因此输入正确也会提示不匹配。
• 全局变量作用域错误：start()函数内修改passwordright时没有声明为全局变量，Python会将其识别为函数局部变量，全局的passwordright永远保持False，导致验证环节无限重复。
• 逻辑冲突：你同时使用了递归调用和while循环处理验证失败场景，两套重试逻辑叠加导致流程完全混乱。

start()

改动说明 #

• 移除了输入的int()转换，直接读取用户输入的字符串和passcode比较
• 函数开头加了global passwordright声明，确保修改的是全局变量
• 把递归重试改成了函数内的while循环重试，移除了冗余的循环逻辑，避免流程混乱
