How to copy first n images from a directory to another directory?

Question

I need to copy the first 1400 images from one directory to another. The code I’ve seen:

fnames = ['{}.app_res_model.tiff'.format{i} for i in range(1400)]
for fname in fnames:
    src = os.path.join(dataset_dir, fname)
    dst = os.path.join(train_dir_input, fname)
    shutil.copyfile(src, dst)

As my images are usually labelled "0app_res_model.tiff", this usually works. However I had to delete some images because of poor quality so that now when the loop gets to 18app_res_model.tiff" it breaks because it cannot find the image.

So my question is: how can I adapt this loop so that it’s no longer about the number in the front but simply the first 1400 images in the dataset?

Thanks

You also need to allow for the possibility that are not as many as 1,400 files in the source directory. How about something like this:

from glob import glob
from os.path import join, basename
from shutil import copyfile

SOURCE_DIR = 'foo'
TARGET_DIR = 'bar'

for tiff in glob(join(SOURCE_DIR, '*.app_res_model.tiff'))[:1_400]:
    copyfile(tiff, join(TARGET_DIR, basename(tiff)))
