示例1: test_reindexing
# 需要導入模塊: from pandas.core.indexes.api import Index [as 別名]
# 或者: from pandas.core.indexes.api.Index import get_indexer_non_unique [as 別名]
def test_reindexing(self):
ci = self.create_index()
oidx = Index(np.array(ci))
for n in [1, 2, 5, len(ci)]:
finder = oidx[np.random.randint(0, len(ci), size=n)]
expected = oidx.get_indexer_non_unique(finder)[0]
actual = ci.get_indexer(finder)
tm.assert_numpy_array_equal(expected, actual)示例2: test_reindexing
# 需要導入模塊: from pandas.core.indexes.api import Index [as 別名]
# 或者: from pandas.core.indexes.api.Index import get_indexer_non_unique [as 別名]

tm.assert_numpy_array_equal(expected, actual)
# see gh-17323
#
# Even when indexer is equal to the
# members in the index, we should
# respect duplicates instead of taking
# the fast-track path.
