numpy.ma.MaskedArray class
是ndarray的子類,旨在處理缺少數據的數字數組。在Numpy MaskedArray .__ ilshift__的幫助下,我們可以將左移的元素偏移MaskedArray.__ilshift__()方法中作為參數提供的值。
用法: numpy.MaskedArray.__ilshift__(other)
返回:self <<= value
範例1:
在此示例中,我們可以看到每個元素都右移了MaskedArray.__ilshift__()方法中作為參數傳遞的值。
# import the important module in python
import numpy as np
# make an array with numpy
gfg = np.ma.array([1, 2, 3, 4, 5])
# applying MaskedArray.__ilshift__() method
print(gfg.__ilshift__(2))
輸出:
[ 4 8 12 16 20]
範例2:
# import the important module in python
import numpy as np
# make an array with numpy
gfg = np.ma.array([[1, 2, 3, 4, 5],
[6, 5, 4, 3, 2]])
# applying MaskedArray.__ilshift__() method
print(gfg.__ilshift__(1))
輸出:
[[ 2 4 6 8 10] [12 10 8 6 4]]
