FWIW, here's a proposed new classmethod that makes it possible to easily
customize the field docstrings but without cluttering the API of the factory
function:
@classmethod
def _set_docstrings(cls, **docstrings):
'''Customize the field docstrings
>>> Point = namedtuple('Point', ['x', 'y'])
>>> Point._set_docstrings(x = 'abscissa', y = 'ordinate')
'''
for fieldname, docstring in docstrings.items():
if fieldname not in cls._fields:
raise ValueError('Fieldname %r does not exist' % fieldname)
new_property = _property(getattr(cls, fieldname), doc=docstring)
setattr(cls, fieldname, new_property)
Note, nothing is needed for the main docstring since it is already writeable:
Point.__doc__ = '2-D Coordinate'
