我有一个数据框df：

        workhours
0       0 days 01:45:13.250000000
1       0 days 04:23:56.723404255
2       0 days 07:11:01.688888888
3       0 days 06:02:48.160000000
4       0 days 06:27:57.280000000
5       0 days 07:00:26.551020408
6       0 days 09:04:01.039215686
7       0 days 08:50:11.941176470
8       0 days 07:30:59.725490196
...

我只想拥有小时，而不是“ =天”。
如何从每一行删除它？

最佳答案

试试这个：

import re

df["workhours"] = df["workhours"].apply(lambda x: re.sub("\d+ days ", "", x))
