This can be used to update docstring of ``module``. set_class : bool Namespace of ``module`` is populated with ``_c.__class__`` instead of just ``_c`` from :func:`_get_c`. )rNz{:^10} {:^14.9g} {:^16} {}) r __class__r namevalueZ _unit_stringZ uncertaintyZ referencesetattrappendformat)r r rrZdoclinesZ set_classrrrrr_set_c(s r)T)TNF)__doc__r__all__rrrrrrs
