通过np.bitwise_and()函数计算输入数组中整数二进制表示的相应位的按位AND运算。
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
您可以按如下方式验证输出。 考虑以下按位AND真值表。
一个 | 乙 | 和 |
---|---|---|
1 | 1 | 1 |
1 | 0 | 0 |
0 | 1 | 0 |
0 | 0 | 0 |
1 | 1 | 0 | 1 | ||
AND | |||||
1 | 0 | 0 | 0 | 1 | |
result | 0 | 0 | 0 | 0 | 1 |
