# Source code for tecplot.exception

    """
    The class hierarchy for |PyTecplot| exceptions are as follows. Exceptions in
    parentheses are Python built-ins from which the |PyTecplot| exceptions
    derive. One can use either the Python native errors or the more specific
    "Tecplot" errors to catch exceptions::

        TecplotError (Exception)
         +--- TecplotInitializationError (ImportError)
         |     +--- TecplotLicenseError
         |     +--- TecplotLibraryNotLoadedError
         |     +--- TecplotLibraryNotFoundError
         +--- TecplotLogicError (AssertionError)
         +--- TecplotLookupError (LookupError)
         |     +--- TecplotIndexError (IndexError)
         |     +--- TecplotKeyError (KeyError)
         +--- TecplotOSError (OSError)
         +--- TecplotRuntimeError (RuntimeError)
         |     +--- TecplotNotImplementedError (NotImplementedError)
         +--- TecplotSystemError (SystemError)
         |     +--- TecplotMacroError
