pandas.Series.dt.seconds

Series.dt.seconds

每个元素的秒数（>= 0 且小于 1 天）。

例子

对于系列：

>>> ser = pd.Series(pd.to_timedelta([1, 2, 3], unit='s'))
>>> ser
0   0 days 00:00:01
1   0 days 00:00:02
2   0 days 00:00:03
dtype: timedelta64[ns]
>>> ser.dt.seconds
0    1
1    2
2    3
dtype: int32

对于 TimedeltaIndex：

>>> tdelta_idx = pd.to_timedelta([1, 2, 3], unit='s')
>>> tdelta_idx
TimedeltaIndex(['0 days 00:00:01', '0 days 00:00:02', '0 days 00:00:03'],
               dtype='timedelta64[ns]', freq=None)
>>> tdelta_idx.seconds
Index([1, 2, 3], dtype='int32')
