Question

我与时区的日期时间索引不同。我想从中提取分钟和小时吗？怎么

我的代码：

df.index = DatetimeIndex(['2015-01-01 09:50:00-05:00', '2015-01-01 10:08:00-05:00',
               '2015-01-01 10:13:00-05:00', '2015-01-01 10:18:00-05:00',
               '2015-01-01 10:23:00-05:00', '2015-01-01 10:28:00-05:00',
               '2015-01-01 10:33:00-05:00', '2015-01-01 10:38:00-05:00',
               '2015-01-01 10:43:00-05:00', '2015-01-01 10:48:00-05:00',
               ...
               '2016-01-31 16:27:00-05:00', '2016-01-31 16:32:00-05:00',
               '2016-01-31 16:37:00-05:00', '2016-01-31 16:42:00-05:00',
               '2016-01-31 16:47:00-05:00', '2016-01-31 16:52:00-05:00',
               '2016-01-31 16:57:00-05:00', '2016-01-31 17:02:00-05:00',
               '2016-01-31 17:07:00-05:00', '2016-01-31 17:12:00-05:00'],
              dtype='datetime64[ns, pytz.FixedOffset(-300)]', name='TIMESTAMP', length=275533, freq=None)
print(df.index.date.hour)

输出：

AttributeError: 'numpy.ndarray' object has no attribute 'hour'

Answer 1

您需要使用dt来访问诸如hour或day之类的属性。

df.index.to_series().dt.hour

Python数据框错误'dtype ='datetime64 [ns，pytz.FixedOffset（-300）]'
