Monitoring a Directory for new mkv and mp4 Files

[deanhystad]

You do not use them. You doing this:

mkv= [2, 4, 6, 8]
mp4= [1, 3, 5, 7]
old_series = [mkv, mp4]

for i in range(1, 10):
    print(i in old_series)

This prints False for all numbers because old_series contains two lists [[2, 4, 6, 8]], [1, 3, 5, 7]], not numbers [1, 2, 3, 4, 5, 6, 7, 8]. You need to "flatten" your list.

To speed things up you should use sets.

import os
import sys
import time

dir_pathmovies = 'T:/latest Movies/_test/'
dir_pathseries = 'T:/Series/test/'
extensions = (".mkv", ".mp4")


def scan_files(directory, old_files):
    new_files = []
    for (dir_path, dir_names, files) in os.walk(directory):
        files = [file for file in files if file[-4:] in extensions]
        new_files += [file for file in files if file not in old_files]
        old_files.update(new_files)
    return new_files


def monitor():
    # Initialize sets of movie and series files.
    series = set()
    movies = set()
    scan_files(dir_pathmovies, movies)
    scan_files(dir_pathseries, series)

    try:
        while True:
            # Check for new series and movies
            for remaining in range(10, 0, -1):
                sys.stdout.write("\r")
                sys.stdout.write(f"{remaining:2d} seconds remaining before new DIRSCAN.")
                sys.stdout.flush()
                time.sleep(1)
            print("\n\nNew Movies:", *scan_files(dir_pathmovies, movies), sep="\n", end="\n\n")
            print("New Series:", *scan_files(dir_pathseries, series), sep="\n", end="\n\n")
    except KeyboardInterrupt:
        exit()


monitor()

And give watchdog a look.
