🏛️ CLASSES

builtins.Exception(builtins.BaseException) → Error → ConversionError
builtins.object → Packer
builtins.object → Unpacker

🐛 class ConversionError(Error)

ConversionError(msg)

Method resolution order:

• ConversionError
• Error
• builtins.Exception
• builtins.BaseException
• builtins.object

Methods inherited from Error:

• __init__(self, msg) — Initialize self. See help(type(self)) for accurate signature.
• __repr__(self) — Return repr(self).
• __str__(self) — Return str(self).

Data descriptors inherited from Error:

• __weakref__ — list of weak references to the object (if defined)

Static methods inherited from builtins.Exception:

• __new__(*args, **kwargs) from builtins.type — Create and return a new object. See help(type) for accurate signature.

Methods inherited from builtins.BaseException:

• __delattr__(self, name, /) — Implement delattr(self, name).
• __getattribute__(self, name, /) — Return getattr(self, name).
• __reduce__(...) — Helper for pickle.
• __setattr__(self, name, value, /) — Implement setattr(self, name, value).
• __setstate__(...)
• with_traceback(...) — Exception.with_traceback(tb) — set self.__traceback__ to tb and return self.

Data descriptors inherited from builtins.BaseException:

• __cause__ — exception cause
• __context__ — exception context
• __dict__
• __suppress_context__
• __traceback__
• args

⚠️ class Error(builtins.Exception)

Error(msg)

Exception class for this module. Use:

except xdrlib.Error as var:
    # var has the Error instance for the exception

Public ivars: msg — contains the message
