Numpy allows you to multiply two arrays without a for loop. this is an example of

NumPy matrix multiplication can be done by the following three methods. • multiply(): element-wise matrix multiplication. • matmul(): matrix product of two arrays. • dot(): dot product of two arrays. If you want element-wise matrix multiplication, you can use multiply() function. import numpy as np arr1 = np.array([[1, 2], [3, 4]]) arr2 = np.array([[5, 6], [7, 8]]) arr_result = np.multiply(arr1, arr2) print(arr_result) Output: [[ 5 12] [21 32]] The below image shows the multiplication operation performed to get the result matrix. Numpy Matrix multiply() If you want the matrix product of two arrays, use matmul() function. import numpy as np arr1 = np.array([[1, 2], [3, 4]]) arr2 = np.array([[5, 6], [7, 8]]) arr_result = np.matmul(arr1, arr2) print(f'Matrix Product of arr1 and arr2 is:\n') Output: Dot Product of arr1 and arr2 is: [[19 22] [43 50]] Dot Product of arr2 and arr1 is: [[23 34] [31 46]] Dot Product of two 1-D arrays is: 17 Recommended Readings: • • • • •

Currently, I am doing this using nested for loops on numpy arrays to fill up a list, taking the minimum value of that list, and storing that value in another list. People Also Read: First, a tip for questions: Even your current loopy code doesn't work, as you're assigning values to output instead of output[i]. Try to make sure that if you're asking for a code refactor your original code works (and other than numpy tags, asking for code refactoring on SO will normally get you downvoted). People Also Read: How to use How to update multiple Numpy arrays in a loop – Stack Overflow zeros(3, dtype=int), array)) does not change the current array but creates a new one and stores it inside the variable array. So for the solution you have to change the values of the array itself, which can be done with array[:]. There is no need to use a loop. arange ( [start, ]stop, [step, ]) to generate a range of numbers. multiply () function can be used to multiply two arrays element by element. On numpy arrays, the * operator can also be used as a shortcut for np.

In this tutorial, you’ll learn how to use Python to multiply lists, including how to multiply list elements by a number and multiply lists with one another. By the end of this tutorial, you’ll have learned how to multiply each element by a number, including how to do this with for loops, list comprehensions and numpy array multiplication. Then, you’ll learn how to multiply lists element-wise, using for loops, list comprehensions, the Python zip() function, and the numpy np.multiply() function. Python lists are a powerful data structure that are used in many different applications. Knowing how to multiply them will be an invaluable tool as you progress on your data science journey. For example, you may have a list that contains the different values for a radius of a circle and want to calculate the area of the circles. You may also have a list of incomes and want to calculate how much of a bonus to give. Let’s get started!
