Introduce an UndefinedModbusException class and use it when the lookup in error_code_to_exception_map fails. Previously that would just throw a KeyError with the contained value, so this change makes it more obvious what actually happened.

The docstrings for all these exception classes are somewhat inconsistent. If you like, I will include a commit making them PEP-257 compliant. |
The __repr__() special method is usually called in place of __str__(), but only if the latter is not defined. However the BaseException class already has a __str__() method, so we need to override that specifically. Note that this change doesn't touch the other cases below where the same problem exists. Initialize the error_code field explicitly using the KeyError argument instead of passing in the whole exception object.
