股票筛选程序：打印完整列表而不是遍历，条件不正确

Question

这是输出。我只想要“嗯”，下一个是“ABT”。 ['MMM'、'ABT'、'ABV'、'ABMD'、'ACN'、'ATVI'、'ADBE'、'AMD'] 尾随市盈率：17.85 股本回报率：54.34% 收入：32.35亿美元 季度收入增长：-5.00% ['MMM'、'ABT'、'ABV'、'ABMD'、'ACN'、'ATVI'、'ADBE'、'AMD'] 尾随市盈率：55.03 股本回报率：8.28% 收入：3072亿美元 季度收入增长：2.00%

我试着让它打印（库存清单[每个库存]），但它给出了一个错误消息

此外，它总是打印else语句（无股票），即使根据yahoo finance，“MMM”同时满足条件1和条件3，因此它应该打印“MMM”的股票行情和基本面
