# 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:
