我有3个coulms，isTrade（表示报价或0/1的交易），daetTime（事件的时间）和tradeBid（交易的交易量。我有值和0我不能为空因为我在计算和聚合它。）
我正在尝试仅对交易进行分组（['isTrade'] == 1）并显示总和(np.sum)，但我也想计算它们的数量。
有没有办法将lambda与countif一起使用（lambda x: x.isnull().count()也会返回0值的数量）？
我试图使用：
groups = df[df['isTrade'] == 1].groupby('dateTime')
grouped = (groups.agg({'tradeBid': [np.sum,lambda x: (x=='tradeBid').count()],}))
但是我收到了错误：
引发TypeError（＆＃34;无效的类型比较＆＃34;）
我尝试过＆＃39; count＆＃39; /＆＃39; nunique＆＃39;但它也计算0，而不是＆lt;＆gt; 0 我found或here的所有答案都引用了父条件，因为我已经在这里使用了isTrade == 1
编辑： 预期结果将是每个dateTime，列tradeBi的总和，值的计数＆gt; 1
添加了数据样本文件：
