pdf_merge.py

import glob
from PyPDF2 import PdfFileMerger
import os
from datetime import datetime

now = datetime.now().isoformat().replace(':', '').replace('-', '').replace('.', '')


def get_pdf_files(dir_):
    files = sorted(glob.glob(f'{dir_}\\*.pdf'))
    return [file for file in files if not os.path.basename(file).startswith('Result')]


def merge_pdfs(pdf_list):
    merger = PdfFileMerger()
    for pdf in pdf_list:
        merger.append(open(pdf, 'rb'))
    with open(f'Result_{now}.pdf', 'wb') as fout:
        merger.write(fout)


if __name__ == '__main__':
    working_dir = os.path.dirname(os.path.realpath(__file__))
    merge_pdfs(get_pdf_files(working_dir))

Concatenates all PDFs in a folder in alphabetic order. Ignore files that begin with 'Result'.
