我试图创建一个标签,以一个str系列取决于什么关键字是包含在str。我一直困惑了一段时间,不知道如何接近它。试过这个:

mirantis['cat_label'] = np.where(pd.Series(mirantis.Mirantis_Address).str.contains('openstack|kubernetes'),'openstack', 'kubernetes')

我想我们需要 extract

L = ['openstack','kubernetes','cloud']
pat = '|'.join(r"\b{}\b".format(x) for x in L)
mirantis['cat_label'] = mirantis.Mirantis_Address.str.extract('('+ pat + ')', expand=False)
print (mirantis.head(10))
                                    Mirantis_Address   cat_label
