Keep latest file and delete all other

Question

In my folder there are many pdf files with date-timestamp format such as shown in the last. I would like to keep the latest file for the day and delete the rest for that day

Answer 1

The following snippet works with the test case given.

files = os.listdir(".")
days = set(fname[8:10] for fname in files)

for d in days:
    f = [i for i in files if i[8:10] == d]
    for x in sorted(f)[:-1]:
        os.remove(x)
