Python求职信息爬虫多输入经if判断过滤不熟悉技能问题求助

核心问题排查 #

• 多技能输入未拆分：直接将输入的逗号分隔字符串（如linux,sql）做遍历操作，实际循环时会逐个读取'l'、'i'、'n'这类单个字符，根本不会匹配完整的技能名称，过滤逻辑完全失效
• 校验逻辑写反：原有逻辑是「如果不熟悉的技能不在职位要求里，就标记为需要过滤」，和预期效果完全相反。正确逻辑应该是「如果职位要求里存在用户不熟悉的技能，才标记为需要过滤」
• break语句位置错误：技能校验结束后直接加了break，会在处理完第一个职位后直接终止整个职位遍历流程，且break写在打印逻辑之前，导致打印代码永远不会执行
• 未调用执行函数：原有代码只定义了find_jobs()，没有主动调用，也是无输出的核心原因之一
