Python numpy 模块，disp() 实例源码
我们从Python开源项目中，提取了以下10个代码示例，用于说明如何使用numpy.disp()。

return (crystal_skewed, crystal_filter2D_skewed)

image_skewed = np.zeros((image.shape[0], ceil((image.shape[1]/np.cos(theta)))+ 50 ))

for j in range(0,image.shape[1]):

#np.disp(xs)

fft_image_skewed = fft.fftshift(fft.fft2(image_skewed))
return image_skewed, fft_image_skewed
# image in reciprocal space
#fft_image = fft.fftshift(fft.fft2(image))
# Create crystal: skewed and unskewed. 2D and 3D.
# create FFTs of these. Filter out one peak.

def disp(mesg, device=None, linefeed=True):
"""
Display a message on a device.
Parameters
----------
mesg : str
Message to display.
device : object
Device to write message. If None, defaults to ``sys.stdout`` which is
very similar to ``print``. `device` needs to have ``write()`` and
``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
--------
Besides ``sys.stdout``, a file-like object can also be used as it has
both required methods:
>>> from StringIO import StringIO
>>> buf = StringIO()
>>> np.disp('"Display" in a file', device=buf)
>>> buf.getvalue()
'"Display" in a file\\n'
