如何从填充有datetime.time值的系列中提取小时，分钟和秒

将列表理解与

time

import datetime as datetimedf = pd.Dataframe({'time': [datetime.time(9, 30, 38),       datetime.time(13, 40, 27),       datetime.time(18, 5, 24),      datetime.time(4, 58, 8),       datetime.time(9, 0, 9)]})print (df)       time0  09:30:381  13:40:272  18:05:243  04:58:084  09:00:09df[['h','m','s']] = pd.Dataframe([(x.hour, x.minute, x.second) for x in df['time']])

或转换为

string

int

df[['h','m','s']] = df['time'].astype(str).str.split(':', expand=True).astype(int)print (df)       time   h   m   s0  09:30:38   9  30  381  13:40:27  13  40  272  18:05:24  18   5  243  04:58:08   4  58   84  09:00:09   9   0   9
