示例1: assert_multiindex_copied
# 需要导入模块: from pandas.util import testing [as 别名]
# 或者: from pandas.util.testing import assert_copy [as 别名]
def assert_multiindex_copied(copy, original):
# Levels should be (at least, shallow copied)
tm.assert_copy(copy.levels, original.levels)
tm.assert_almost_equal(copy.codes, original.codes)
# Labels doesn't matter which way copied
tm.assert_almost_equal(copy.codes, original.codes)
assert copy.codes is not original.codes
# Names doesn't matter which way copied
assert copy.names == original.names
assert copy.names is not original.names
# Sort order should be copied
assert copy.sortorder == original.sortorder 示例2: test_astype
# 需要导入模块: from pandas.util import testing [as 别名]
# 或者: from pandas.util.testing import assert_copy [as 别名]
