numpy.invert()

This function computes the bitwise NOT result on integers in the input array. For signed integers, two's complement is returned.

Example

import numpy as np 

print 'Invert of 13 where dtype of ndarray is uint8:' 
print np.invert(np.array([13], dtype = np.uint8)) 
print '\n'  
# Comparing binary representation of 13 and 242, we find the inversion of bits 

print 'Binary representation of 13:' 
print np.binary_repr(13, width = 8) 
print '\n'  

print 'Binary representation of 242:' 
print np.binary_repr(242, width = 8)

Its output is as follows −

Invert of 13 where dtype of ndarray is uint8:
[242]

Binary representation of 13:
00001101

Binary representation of 242:
11110010

Note that np.binary_repr() function returns the binary representation of the decimal number in the given width.
