Python 请帮助解决此问题

问题出在这一行：

如果您试图通过索引日期获取

使用sch.loc[]

因为你还没有发布数据。我只能说调试这个sch[new_date]部分

请让你的问题更具体一些。我建议你给出today_date=dt.date.today.strftime'%Y-%m-%d'和new_date=dt.date.today.strftime'%Y-%m-%d 00:00'也是lob['Schedule']日期时间列或字符串对象列？你正在使用sch['2021-03-18 00:00:00']我想你没有写2021-03-18 00:00:00的专栏？所以你会得到错误。解释你想用2021-03-18 00:00:00做什么？你想得到2021-03-18 00:00:00这一天的所有值吗？它没有帮助，同样的错误来了，你能帮我吗。我将向您提供数据want@SunnyR：只需发布一些数据样本。大学教师；我不需要把所有的数据都放进去。我们可以在别的地方谈一谈吗？我把代码和输出展示给你，这样对你来说就更清楚了understand@SunnyR当前位置邀请我这样聊天。但我现在帮不了你。晚上9点左右见。现在去ofc。cyaok将在9点前接通
