示例1: __getstate__

# 或者: from numpy.ndarray import tobytes [as 别名]
def __getstate__(self):
"""Return the internal state of the masked array, for pickling
purposes.
"""

# 或者: from numpy.ndarray import tobytes [as 别名]
def tostring(self, fill_value=None, order='C'):
"""
This function is a compatibility alias for tobytes. Despite its name it
returns bytes not strings.
"""
return self.tobytes(fill_value, order='C') 示例3: tobytes
# 需要导入模块: from numpy import ndarray [as 别名]
# 或者: from numpy.ndarray import tobytes [as 别名]
def tobytes(self, fill_value=None, order='C'):
"""
Return the array data as a string containing the raw bytes in the array.
The array is filled with a fill value before the string conversion.
.. versionadded:: 1.9.0
Parameters
----------
fill_value : scalar, optional
Value used to fill in the masked values. Deafult is None, in which
case `MaskedArray.fill_value` is used.
order : {'C','F','A'}, optional
Order of the data item in the copy. Default is 'C'.
- 'C' -- C order (row major).
- 'F' -- Fortran order (column major).
- 'A' -- Any, current order of array.
- None -- Same as 'A'.

Notes
-----
As for `ndarray.tobytes`, information about the shape, dtype, etc.,
but also about `fill_value`, will be lost.
Examples
--------
>>> x = np.ma.array(np.array([[1, 2], [3, 4]]), mask=[[0, 1], [1, 0]])
>>> x.tobytes()
'\\x01\\x00\\x00\\x00?B\\x0f\\x00?B\\x0f\\x00\\x04\\x00\\x00\\x00'
