@GuessWhoSamFoo inspiration from your PR. these grouping tests were all over the place.

if you can rebase on top of this (and put your test in the test_grouping.py would be great), if not I can do it after.

You could a namedtuple to expand the tuple which would address the failed tests and would also enable use of keywords in cases where tuple expansion was used with the old string formatting:

```python
UnicodeDataCol = namedtuple('UnicodeDataCol',  ['name', 'cname', 'dtype', 'kind', 'shape'])
def __unicode__(self):
        temp = UnicodeDataCol(
            *map(pprint_thing,
                 (self.name,
                  self.cname,
                  self.dtype,
                  self.kind,
                  self.shape)))
        return ("name->{name},cname->{cname},dtype->{dtype},kind->{kind},"
                "shape->{shape}".format(name=temp.name, cname=temp.cname,
                                        dtype=temp.dtype, kind=temp.kind,

Closes #17958.

looks fine. will merge after we release.
thanks!
