过滤系列与timedelta范围

Question

我有三个数据集，所有数据集都是timedelta64：

Line 2: SyntaxError: near '(order by Score) Rank
from Scores
order by Score desc'

我申请了：

data1
1   17:49:43
2   09:44:37
3   10:45:52
4   12:58:31
5   16:09:18
6   14:42:53
7   16:19:24
8   15:13:03
9   13:56:40

data2
1   17:50:17
2   09:47:09
3   10:46:10
4   13:02:13
5   16:09:16
6   14:46:14
7   16:20:16
8   15:14:15
9   14:04:14

data3
1   00:00:34
2   00:02:32
3   00:00:18
4   00:03:42
5   23:59:58
6   00:03:21
7   00:00:52
8   00:01:12
9   00:07:34

然后，我收到了一个错误：

df_temp = data3['14:00:00' < data1 < '14:50:00'].mean()

我该如何纠正？

Answer 1

解决此问题的一种方法是转换为秒并只比较整数：

x, y = pd.to_timedelta('14:00:00').seconds, pd.to_timedelta('14:50:00').seconds

df_temp = data3[data1.dt.seconds.between(x, y)].mean()
