### Notes

## Classes

### `IPythonCoreError`

class `IPython.core.error.``IPythonCoreError`

  Bases: `exceptions.Exception`

  `__init__`()

    x.__init__(...) initializes x; see help(type(x)) for signature

  `args`
  `message`

### `StdinNotImplementedError`

class `IPython.core.error.``StdinNotImplementedError`

  Bases: `IPython.core.error.IPythonCoreError`, `exceptions.NotImplementedError`

  raw_input was requested in a context where it is not supported

  For use in IPython kernels, where only some frontends may support stdin requests.

  `__init__`()

    x.__init__(...) initializes x; see help(type(x)) for signature

  `args`
  `message`

### `TryNext`

class `IPython.core.error.``TryNext`(*args, **kwargs)

  Bases: `IPython.core.error.IPythonCoreError`

  Try next hook exception.

  Raise this in your hook function to indicate that the next hook handler should be used to handle the operation. If you pass arguments to the constructor those arguments will be used by the next hook instead of the original ones.

  `__init__`(*args, **kwargs)
  `args`
  `message`

### `UsageError`

class `IPython.core.error.``UsageError`

  Bases: `IPython.core.error.IPythonCoreError`

  Error in magic function arguments, etc.

  Something that probably won’t warrant a full traceback, but should nevertheless interrupt a macro / batch file.

  `__init__`()

    x.__init__(...) initializes x; see help(type(x)) for signature

  `args`
  `message`
