This will force repeat the field names twice.

If we have such docs_dict, we can use it as:

field_names = ['x', 'y']
Point = namedtuple('Point', field_names,
     field_docs=list(map(docs_dict.get, field_names)))

or as

Point = namedtuple('Point',
     [(f, docs_dict.get(f)) for f in field_names])

In case of ordered dict it can be even simpler:

Point = namedtuple('Point', ordered_dict.keys(),
     field_docs=list(ordered_dict.values()))

or

Point = namedtuple('Point', ordered_dict.items())
