Python standardize_mapping Examples

Example #1

File: test_common.py Project: DusanMilunovic/pandas

def test_standardize_mapping():
    # No uninitialized defaultdicts
    with pytest.raises(TypeError):
        com.standardize_mapping(collections.defaultdict)

    # No non-mapping subtypes, instance
    with pytest.raises(TypeError):

    # No non-mapping subtypes, class
    with pytest.raises(TypeError):

    # Convert instance to type
    assert (com.standardize_mapping({}) == dict)

    dd = collections.defaultdict(list)
    assert isinstance(com.standardize_mapping(dd), partial)
