right_shift
numpy.right_shift()函数将数组元素的二进制表示中的位numpy.right_shift()移位指定的位置，并从左侧追加相等数量的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.
其产出如下 -
Right shift 40 by two positions:
10
Binary representation of 40:
00101000
Binary representation of 10
00001010
