WebA typical numpy array function for creating an array looks something like this: numpy. array (object, dtype =None, copy =True, order ='K', subok =False, ndmin =0) Here, all attributes other than objects are optional. So, do not worry even if you do not understand a lot about other parameters. Object: specify the object for which you want an array. WebJul 21, 2010 · numpy.bitwise_or. ¶. Compute the bit-wise OR of two arrays element-wise. Computes the bit-wise OR of the underlying binary representation of the integers in the input arrays. This ufunc implements the C/Python operator . Only integer types are handled (including booleans). Array into which the output is placed.

WebApr 26, 2024 · A very simple way which does not require the use of any special method such as np.where() is to get the indices for the conditions of the variables in your numpy array, and accordingly assign the required value (in your case 0 for 1s and 1 for 0s) to the respective positional items in the array.This works for values other than 0s and 1s too. …

WebOct 11, 2024 · Initialize an integer variable, say bitwise_OR_sum with 0. Traverse in the range [0, 31] using variable j. If the j th bit is set in the binary representation of arr2[i], then increment bitwise_OR_sum by N * 2 j. Otherwise, increment by frequency[j] * 2 j; Print the sum obtained bitwise_OR_sum.
