- class pymbs.exceptions.GracefulMessage(message, **kwargs)[source]¶
Bases:
object
The GracefulMessage object allows various messages to be displayed in the most appropriate format, depending on how PyMBS is being used at the time.
If PyMBS is being used in something like a Jupyter Notebook, where HTML can be displayed, it will display HTML. If the front-end is only capable of displaying text, it will display plain text.
TODO: Implement a _repr_json_ method to output the error message as a JSON string, for when PyMBS is integrated with a RESTful/GraphQL API.

message templates of the GracefulMessage object.
