Just rotate image

Question

what is my mistake?

I just want to rotate original image and save him to output folder.

from pathlib import Path
from PIL import Image, ImageFilter

for image in Path('/home/lol/Pictures').glob('**/*.png'):
    img = Image.open(image)
    img = img.rotate(180)
    img.save('/home/lol/Pictures/output/{}'.format(image.name))

    print('Done: {}'.format(image))

Console output:

Done: /home/lol/Pictures/image.png
Done: /home/lol/Pictures/output/image.png

And the picture in output is the same like original.

It looks like the script is successfully rotating Pictures/image.png and saving it in your output directory. But it doesn't stop there: glob iterates its way into the output folder, and rotates all of those pictures too. So your original output/image.png gets overwritten with a copy of output/image.png, except rotated 180 degrees. In other words, it's your original image, rotated 360 degrees - an identical copy.

You should make sure that glob doesn't iterate over the output directory. You could move output to somewhere other than home/lol/Pictures. Or perhaps you could manually skip over the output directory, with something like if "/output/" in image: continue.
