无涯教程-NumPy - 右移运算符函数

numpy.right_shift()函数将数组元素的二进制表示形式向右移动指定的位置，并在左侧添加相等数量的0。

import numpy as np 

print 'Right shift 40 by two positions:' 
print np.right_shift(40,2) 
print '\n'  

print 'Binary representation of 40:' 
print np.binary_repr(40, width=8) 
print '\n'  

print 'Binary representation of 10' 
print np.binary_repr(10, width=8)  
# Two bits in '00001010' are shifted to right and two 0s appended from left.

其输出如下-

Right shift 40 by two positions:
10

Binary representation of 40:
00101000

Binary representation of 10
00001010
