Web22 ian. 2024 · Multiply two Lists in Python by Using NumPy. Another method is to use the NumPy library. First, we convert both lists to NumPy arrays or ndarrays, i.e., arr1 and arr2. Then, we multiply two arrays like we do numbers, i.e., arr1*arr2. Finally, we convert the ndarray to a list. However, the length of both lists needs to be the same.
