Function printoptions

numpy/_core/arrayprint.py:398–435

Context manager for setting print options. Set print options for the scope of the `with` block, and restore the old options at the end. See `set_printoptions` for the full description of available options. Examples -------- >>> import numpy as np >>> from numpy.testing

    """Context manager for setting print options.

    Set print options for the scope of the `with` block, and restore the old
    options at the end. See `set_printoptions` for the full description of
    available options.

    Examples
    --------
    >>> import numpy as np

    >>> from numpy.testing import assert_equal
    >>> with np.printoptions(precision=2):
    ...     np.array([2.0]) / 3
    array([0.67])

    The `as`-clause of the `with`-statement gives the current print options:

    >>> with np.printoptions(precision=2) as opts:
    ...      assert_equal(opts, np.get_printoptions())

    See Also
    --------
    set_printoptions, get_printoptions

    Notes
    -----
    These print options apply only to NumPy ndarrays, not to scalars.

    **Concurrency note:** see :ref:`text_formatting_options`
