Want to get image size in kilobytes using python

Question

I am trying to get the image name, resolution, and size of the image from the directory. I got image name, resolution and size but image size is not in kilobytes it is getting like pixels. so please suggest me how to get the image size with the python script.

    # Required Libraries
from os import listdir
from os.path import isfile, join
from pathlib import Path
import numpy
import cv2
import argparse
import numpy
import csv
from PIL import Image
  
# Check whether the CSV 
# exists or not if not then create one.
my_file = Path("csv/details.csv")
  
if my_file.is_file():
    f = open(my_file, "w+")
    with open('csv/details.csv', 'a', newline='') as file:
        writer = csv.writer(file)
          
        writer.writerow(["S.No.", "Name", "Resolution", "Size"
                        ])
    f.close()
    pass
    
else:
    with open('csv/details.csv', 'w', newline = '') as file:
        writer = csv.writer(file)
          
        writer.writerow(["S.No.", "Name", "Resolution", "Size"
                        ])
  
# Argparse function to get
# the path of the image directory
ap = argparse.ArgumentParser()
  
ap.add_argument("-i", "--image", 
                required = True, 
                help = "Path to folder")
  
args = vars(ap.parse_args())
  
# Program to find the
# colors and embed in the CSV
mypath = args["image"]
  
onlyfiles = [ f for f in listdir(mypath) if isfile(join(mypath,f)) ]
images = numpy.empty(len(onlyfiles), dtype = object)
  
for n in range(0, len(onlyfiles)):
    
    path = join(mypath,onlyfiles[n])
    images[n] = cv2.imread(join(mypath,onlyfiles[n]),
                           cv2.IMREAD_UNCHANGED)
      
    img = cv2.imread(path)
    h,w,c = img.shape
    resolution = f"{h} X {w}"
    size = img.size
    print(h, w)
      
    avg_color_per_row = numpy.average(img, axis = 0)
    avg_color = numpy.average(avg_color_per_row, axis = 0)
      
    with open('csv/details.csv', 'a', newline = '') as file:
        writer = csv.writer(file)
        writer.writerow([n+1, onlyfiles[n], resolution, size  
                        ])
        file.close() 

and also please find below is the screenshot for your reference.

Hi you can use this inside your for loop

import os

file_size = os.path.getsize('d:/file.jpg')
print("File Size is :", file_size, "bytes")
