借助Numpy numpy.ndarray.__lshift__()
方法,我們可以將元素左移的值作為參數提供給numpy.ndarray.__lshift__()
方法。
用法:ndarray.__lshift__($self, value, /)
返回:自
範例1:
在此示例中,我們可以看到每個元素都左移了作為參數傳遞給ndarray.__lshift__()
方法。
# import the important module in python
import numpy as np
# make an array with numpy
gfg = np.array([1, 2, 3, 4, 5])
# applying ndarray.__lshift__() method
print(gfg.__lshift__(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.array([[1, 2, 3, 4, 5],
[6, 5, 4, 3, 2]])
# applying ndarray.__lshift__() method
print(gfg.__lshift__(1))
輸出:
[[ 2 4 6 8 10] [12 10 8 6 4]]
