Python Blackjack游戏while循环未退出问题求助（禁用break）

核心问题 #

1. Ace值调整后未更新分数
   当用户手牌里的11（Ace）导致爆牌时，代码把11改成了1，但没重新计算user_score。比如实际分数已经降到21以下，user_score还是原来的爆牌数值，逻辑判断全错，循环自然退不出去。
2. 状态更新后仍执行冗余代码
   就算把should_continue设成了False，循环里后面的line_gap()和询问要牌的代码还是会跑，程序还会问你要不要牌，根本没法退出。
3. 最终结算时电脑分数没更新
   final_score_calculation函数里给电脑补了牌，但没重新算computer_score，最后显示的分数是错的。

修复方案 #

1. 改完Ace值立刻更新分数
   把11换成1之后，马上调用calculate_score更新user_score或computer_score，保证后续判断用的是最新分数。
2. 用条件跳过冗余代码
   一旦设置了should_continue = False，就跳过后面的询问要牌逻辑，别再执行无效操作。
3. 结算前更新电脑分数
   在final_score_calculation里给电脑补完牌后，重新计算computer_score。
