I have a dataset of thousands of images downloaded from Kaggle and am wanting to rename the files. The images are all .png images. The current names of the images are all similar to 'Screen Shot 2018-06-08 at 5.08.37 PM.png' and am wanting to just rename them all to simple numbers (ex: 0.png, 1.png, 2.png, ..., 1234.png).
I am using a smaller dataset to test out code and see there is a rename() function in the os module. I currently have:
for count, filename in enumerate(os.listdir(data_dir_path)):
dst = str(count) + '.png'
src = str(data_dir_path) + '/' + filename
dst = str(data_dir_path) + '/' + dst
os.rename(dst, src)
This worked, however before I ran the script I had around 16 images, and now after running this script, I now only have the first 8.
data_dir_path = '/content/drive/MyDrive/Fruits/train/Fresh Apples/'
You have src and dst the wrong way round in os.rename(dst, src).
It's also a good idea to use os.path.join() instead of manually concatenating the separator / (let Python take care of it for you, and it will work across *nix/Windows/Mac):
for count, filename in enumerate(os.listdir(data_dir_path)):
src = os.path.join(data_dir_path, filename)
dst = os.path.join(data_dir_path, f'{str(count)}.png')
os.rename(src, dst)
