Broadcasting mechanism of NumPy binary operation

There is a very convenient feature in NumPy: broadcasting. When we perform binary calculations (such as addition, multiplication) on two numpy arrays of different lengths, broadcasting works silently behind the scenes. In this article, we will introduce numpy broadcasting. What is broadcastingLet's get to know broadcasting through a simple example, consider the following codeimport numpy as np a = np.array([0, 1, 2]) b = np.array([5, 5, 5]) c = a + ba+b actually adds each pair of elements at the
