对于pd.interval，Pandas.Series.dtype.kind为None [英] Pandas.Series.dtype.kind is None for pd.interval
本文介绍了对于pd.interval，Pandas.Series.dtype.kind为None的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
测试代码:
s = pd.Series(pd.array([pd.Interval(0,1.2), pd.Interval(5,123)]))
s.dtype
s.dtype.kind is None
>>> interval[float64]
>>> True
是一些错误还是故意制作的?如果是后者-是出于什么原因?
Is it some bug or made intentionally? If latter - for what reason?
推荐答案
之所以显示为None的原因仅仅是因为IntervalDtype的实现此处).
The reason this is appearing as None is simply because the implementation of IntervalDtype explicitly sets kind = None. This should probably be updated to 'O', though some care is needed here as it will result in unintended side effects, e.g. this would cause is_string_dtype to return True (see here).
