与运算符函数

输入数组中整数的二进制按位与(and)运算由np.bitwise_and()函数计算。

import numpy as np 
print 'Binary equivalents of 13 and 17:' 
a,b=13,17 
print bin(a), bin(b) 
print '\n'  

print 'Bitwise AND of 13 and 17:' 
print np.bitwise_and(13, 17)

其输出如下-

Binary equivalents of 13 and 17:
0b1101 0b10001

Bitwise AND of 13 and 17:
1
