NumPy - 按位与
-
简述
输入数组中整数二进制表示的相应位的按位与运算由 np.bitwise_and() 函数计算。 -
例子
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)
它的输出如下 -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。考虑以下按位与真值表。A B AND 1 1 1 1 0 0 0 1 0 0 0 0 1 1 0 1 AND 1 0 0 0 1 结果 0 0 0 0 1
