``flush()`` methods.
linefeed : bool, optional
    Option whether to print a line feed or not. Defaults to True.

Raises
------
AttributeError
    If `device` does not have a ``write()`` or ``flush()`` method.

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

Besides ``sys.stdout``, a file-like object can also be used as it has
both required methods:

>>> from io import StringIO
>>> buf = StringIO()
>>> np.disp('"Display" in a file', device=buf)
>>> buf.getvalue()
'"Display" in a file\n'

zW`disp` is deprecated, use your own printing function instead. (deprecated in NumPy 2.0)rŠ
