NumPy - bitwise_and



The bitwise AND operation on the corresponding bits of binary representations of integers in input arrays is computed by np.bitwise_and() function.

Example

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)

Its output is as follows −

Binary equivalents of 13 and 17:
0b1101 0b10001

Bitwise AND of 13 and 17:
1

You can verify the output as follows. Consider the following bitwise AND truth table.

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
result 0 0 0 0 1
