numpy.bitwise_or() in Python

numpy.bitwise_or()function is used to Compute the bit-wise OR of two array element-wise. This function computes the bit-wise OR of the underlying binary representation of the integers in the input arrays.

Syntax : numpy.bitwise_or(arr1, arr2, /, out=None, *, where=True, casting=’same_kind’, order=’K’, dtype=None, ufunc ‘bitwise_or’)

Parameters :
arr1 : [array_like] Input array.
arr2 : [array_like] Input array.

out : [ndarray, optional] A location into which the result is stored.
  -> If provided, it must have a shape that the inputs broadcast to.
  -> If not provided or None, a freshly-allocated array is returned.
**kwargs : allows you to pass keyword variable length of argument to a function. It is used when we want to handle named argument in a function.
where : [array_like, optional]True value means to calculate the universal functions(ufunc) at that position, False value means to leave the value in the output alone.

Return : [ndarray or scalar] Result. This is a scalar if both x1 and x2 are scalars.

Code #1 : Working




# Python program explaining
# bitwise_or() function
  
import numpy as geek
in_num1 = 10
in_num2 = 11
  
print ("Input  number1 : ", in_num1)
print ("Input  number2 : ", in_num2) 
    
out_num = geek.bitwise_or(in_num1, in_num2) 
print ("bitwise_or of 10 and 11 : ", out_num) 


Output :

Input  number1 :  10
Input  number2 :  11
bitwise_or of 10 and 11 :  11

 
Code #2 :




# Python program explaining
# bitwise_or() function
  
import numpy as geek
  
in_arr1 = [2, 8, 125]
in_arr2 = [3, 3, 115]
   
print ("Input array1 : ", in_arr1) 
print ("Input array2 : ", in_arr2)
    
out_arr = geek.bitwise_or(in_arr1, in_arr2) 
print ("Output array after bitwise_or: ", out_arr) 


Output :

Input array1 :  [2, 8, 125]
Input array2 :  [3, 3, 115]
Output array after bitwise_or:  [  3  11 127]

 
Code #3 :




# Python program explaining
# bitwise_or() function
  
import numpy as geek
  
in_arr1 = [True, False, True, False]
in_arr2 = [False, False, True, True]
   
print ("Input array1 : ", in_arr1) 
print ("Input array2 : ", in_arr2)
    
out_arr = geek.bitwise_or(in_arr1, in_arr2) 
print ("Output array after bitwise_or: ", out_arr) 


Output :

Input array1 :  [True, False, True, False]
Input array2 :  [False, False, True, True]
Output array after bitwise_or:  [ True False  True  True]
