Python is not reading my .jpg/.tiff/.png file in sequence

Question

import glob
for file in glob.glob('images/scratch_assay/*[0-9].*'):
print(file)

Does this answer your question? [How are glob.glob()'s return values ordered?](https://stackoverflow.com/questions/6773584/how-are-glob-globs-return-values-ordered) — w-m, Sep 27 '22 at 13:10
As you don't have leading zeroes, you will to perform a natural sort on your list of file paths. — w-m, Sep 27 '22 at 13:12

You can sort the returned list with sorted(glob.glob('images/scratch_assay/*[0-9].*'))

But consider that sorting alphabetically means that "10" will come just after "1", so the sequence will be 1, 10, 2, 3, 4, 5, 6, 7, 8, 9

To avoid that the simplest way is probably to pad the filenames with a leading zero ("01", "02", "03", etc)
