Rewrite Image after applying sharpening filter to it

I have to sharpen an image and use it for further process.I found a code based on OpenCv which would do the work but instead of just displaying I want to save the image after applying the affects.Also this is just for a single image I want to apply for a folder of images. The sharpening code is below:

import cv2
import numpy as np
# Reading in and displaying our image
image = cv2.imread('images/input.jpg')
cv2.imshow('Original', image)
# Create our shapening kernel, it must equal to one eventually
kernel_sharpening = np.array([[-1,-1,-1], 
                              [-1, 9,-1],
                              [-1,-1,-1]])
# applying the sharpening kernel to the input image & displaying it.
sharpened = cv2.filter2D(image, -1, kernel_sharpening)
cv2.imshow('Image Sharpening', sharpened)
cv2.waitKey(0)
cv2.destroyAllWindows()

According to the documentation:

Write an image Use the function cv2.imwrite() to save an image.

First argument is the file name, second argument is the image you want to save.

cv2.imwrite('messigray.png',img)

You can just use:

cv2.imwrite('images/input.jpg', image)

after

sharpened = cv2.filter2D(image, -1, kernel_sharpening)

and something like:

for im_path in im_paths:
   image = cv2.imread(im_path)
   ...

where you just replace your hardcoded path with im_path.

Anyway this is fundamental research, for example, and you should apply this before asking questions here.
