Web10 feb. 2024 · Numpy Server Side Programming Programming To construct an array by executing a function over each coordinate, use the numpy.fromfunction () method in Python Numpy. The function is called with N parameters, where N is the rank of shape. Each parameter represents the coordinates of the array varying along a specific axis. WebIf you specify axis=1, NumPy will return the product of each array. Example Get your own Python Server Perform summation in the following array over 1st axis: import numpy as np arr1 = np.array ( [1, 2, 3, 4]) arr2 = np.array ( [5, 6, 7, 8]) newarr = np.prod ( [arr1, arr2], axis=1) print(newarr) Try it Yourself » Returns: [24 1680] gijoeelectronics.com
