Python编写RPG角色卡加点系统时技能点数耗尽无法结束循环求助

• 主循环判断条件仅校验end == 0，未关联剩余技能点数lvlpts，就算点数耗尽也会进入下一轮循环
• 所有技能分支的点数充足判断写了无用恒真条件or(amountpt == amountpt)，导致点数不足时也会执行扣点逻辑，甚至把lvlpts扣为负数
• 编号5对应耐力技能的逻辑顺序和其他分支不一致，先做点数校验再做扣点，其他分支先扣点再校验，逻辑混乱
• 各个分支中lvlpts == 0时触发的break只能跳出当前层级代码块，部分场景下无法终止最外层的主循环

1. 修改主循环条件，直接关联剩余点数，点数耗尽自动终止循环，无需额外判断
2. 删除所有分支中的无用恒真判断，保留有效的点数充足校验
3. 统一所有技能分支的逻辑顺序：先校验输入点数是否充足，不足则循环让用户重新输入，确认充足后再执行加技能、扣点数操作
4. 优化退出判断逻辑，和主循环的end变量关联，逻辑更统一
