Read images from from the folder in the same order in which they appears and store in the same order

I have 10k images in one folder. In that, I have images in the order, 0.jpg, 1.jpg, 2.jpg to 10000.jpg. I have to read the images in the same order, process them, and store them in the same order. I have used the below code. But I can't get the expected output. Randomly it is reading files from the folder so, the output folder is randomly ordered. What should I change?

path = "location of the image folder"
i=0
for fname in os.listdir(path):    
    img = imageio.imread(path + '/' + fname)
    img_aug = seq.augment_image(img) # perform imgaug library data augmentation
    imageio.imwrite(os.path.join(path, path+ '/output/'+ "%1d.jpg" % (i,)), img_aug)
    print(i)
    i += 1

The updated code is:

path = "location of the image folder"
i=0
list_dir=[int(file.split(".")[0]) for file in os.listdir(path)]
list_dir.sort()
for fname in list_dir:    
    img = imageio.imread(path + '/' + str(fname)+".jpg")
    img_aug = seq.augment_image(img) # perform imgaug library data augmentation
    imageio.imwrite(os.path.join(path, path+ '/output/'+ "%1d.jpg" % (i,)), img_aug)
    print(i)
    i += 1

I'm assuming all the images in the directory are .jpg images. I have just extracted the file no for all files in the directory and sorted them as integers. Hope this helps
