Merge Two Array Python Code Example
What is compared are values not types So an int 1 and an array of length one can evaluate as True np equal 1 np ones 1 array True The operator can be used as a shorthand for np equal on ndarrays a np array 2 4 6 b np array 2 4 2 a b array True True False Numpy equal NumPy v1 26 Manual. The easiest way to compare two NumPy arrays is to Create a comparison array by calling between two arrays Call all method for the result array object to check if the elements are True Here is an example import numpy as np A np array 1 1 2 2 B np array 1 1 2 2 equal arrays A B all print equal arrays Parameters aarray like Input array nint optional The number of times values are differenced If zero the input is returned as is axisint optional The axis along which the difference is taken default is the last axis prepend appendarray like optional Values to prepend or append to a along axis prior to performing the difference
