Hi@akhtar,

This convolution function is a part of your numpy. So you have to import your numpy module. And also create two arrays as shown below.

import numpy as np
arr = np.array([0,0,0,1,1,1,0,0,0])
arr2=np.array([10,-10])

To perform convolution you have to pass these two array as follows.

np.convolve(arr,arr1)
