# Module: `utils.capture`

IO capturing utilities.

## 3 Classes

class `IPython.utils.capture.``RichOutput`(data=None, metadata=None)

  Bases: `object`

  `__init__`(data=None, metadata=None)

class `IPython.utils.capture.``CapturedIO`(stdout, stderr, outputs=None)

  Bases: `object`

  Simple object for containing captured stdout/err and rich display StringIO objects

  Each instance `c` has three attributes:

  - `c.stdout` : standard output as a string
  - `c.stderr` : standard error as a string
  - `c.outputs`: a list of rich display outputs

  Additionally, there’s a `c.show()` method which will print all of the above in the same order, and can be invoked simply via `c()`.

  `__init__`(stdout, stderr, outputs=None)
  `outputs`

    A list of the captured rich display outputs, if any.

    If you have a CapturedIO object `c`, these can be displayed in IPython using:

        from IPython.display import display
        for o in c.outputs:
            display(o)

  `show`()

    write my output to sys.stdout/err as appropriate

  `stderr`

    Captured standard error

  `stdout`

    Captured standard output

class `IPython.utils.capture.``capture_output`(stdout=True, stderr=True, display=True)

  Bases: `object`

  context manager for capturing stdout/err

  `__init__`(stdout=True, stderr=True, display=True)
