Python| numpy numpy.ndarray.__lshift__()
在Numpy numpy.ndarray.__lshift__()
方法的帮助下,我们可以通过numpy.ndarray.__lshift__()
方法中作为参数提供的值获得左移的元素。
Syntax: ndarray.__lshift__($self, value, /)
Return: self<
示例 #1:
在这个例子中,我们可以看到每个元素都左移了作为ndarray.__lshift__()
方法中的参数传递的值。
# 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))
输出:
[ 4 8 12 16 20]
示例 #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))
输出:
[[ 2 4 6 8 10]
[12 10 8 6 4]]
