Python File with Zip – Created Yesterday

Look for file and folder created yesterday

The python script below gets the newest file and directory created yesterday. The file and directory must match a pattern.

The file and directory are then zipped. The source file and directory remain on the drive.

import os
import datetime
import re
import shutil
import tarfile

def get_newest_in_previous_day(path):
    previous_day_files = []
    previous_day_dirs = []

    previous_day = (datetime.datetime.now() - datetime.timedelta(days=1))
    pattern = re.compile(r"\d{4}-\d{2}-\d{2}T\d{2}:\d{2}:\d{2}Z(\.pbm\.json)?$")

    for name in os.listdir(path):
        # Skip names that do not match the pattern
        if not pattern.match(name):
            continue

        full_path = os.path.join(path, name)
        timestamp_str = name.split('T')[0]  # Extract the date part from the name
        timestamp = datetime.datetime.strptime(timestamp_str, "%Y-%m-%d")

        # Check if it's the previous day
        if timestamp.date() == previous_day.date():
            if os.path.isfile(full_path):
                previous_day_files.append((timestamp, name))
            elif os.path.isdir(full_path):
                previous_day_dirs.append((timestamp, name))

    # Sort by timestamp (newest first) and get the first name
    previous_day_files.sort(reverse=True)
    previous_day_dirs.sort(reverse=True)

    newest_file = previous_day_files[0][1] if previous_day_files else None
    newest_dir = previous_day_dirs[0][1] if previous_day_dirs else None

    gzip_name = previous_day.strftime("%Y-%m-%d-Database.gzip")
    gzip_file_path = os.path.join(path, gzip_name)

    # If both the file and directory exist, compress them
    if newest_file and newest_dir:
        with tarfile.open(gzip_file_path, "w:gz") as tar:
            tar.add(os.path.join(path, newest_file))
            tar.add(os.path.join(path, newest_dir))

        print("File and directory were zipped.")
    else:
        print("Nothing was zipped.")

    return newest_file, newest_dir
