How to Perform Sum Product Function in Python
The sum product function in Python is used to calculate the sum of the products of two or more arrays. This can be achieved using the NumPy library in Python. Here's how to do it:
First, you need to install the NumPy library using the following command:
pip install numpy
Once you have installed the NumPy library, you can import it into your Python code using the following command:
import numpy as np
Next, you can use the np.sum() function to calculate the sum product. Here's an example:
a = np.array([1, 2, 3]) b = np.array([4, 5, 6]) sum_product = np.sum(a * b) print(sum_product)
You can take this one step further and add it to a file that has a whole array of functions you commonly use in it. To do so, add the function below to said file:
def sum_product(a:list, b:list): a = np.array(a) b = np.array([b]) sum_product = np.sum(a * b) return sum_product)
