Question

I have a python script that checks a certain folder for new files and then copies the new files to another directory. The files are in such a format 1234.txt and 1234_status.txt. It should only move 1234.txt and leave the 1234_status.txt unattended.

Here’s a little piece of my code in python

    while 1:
#retrieves listdir
        after = dict([(f, None) for f in os.listdir (path_to_watch)])
#if after has more files than before, then it adds the new files to an array "added"
        added = [f for f in after if not f in before]

My idea is that after it fills added, then it checks it for values that have status in it and pops it from the array. Couldn’t find a way to do this though : /

Answer 1

added = [f for f in after if not f in before and '_status' not in f]

I do however recommend to refrain from long one line statements as they make the code almost impossible to read
