Merging all pdf files in a folder into one pdf with pypdf2

Question

I want to merge all the PDFs in a directory with PyPDF2.

I tried the code from pypdf Merging multiple pdf files into one pdf

from PyPDF2 import PdfFileMerger, PdfFileReader

merger = PdfFileMerger()

for filename in os.listdir():
    merger.append(PdfFileReader(file(filename, 'rb')))

merger.write('Result.pdf')

I got an error!

NameError: name 'file' is not defined

I tried using `open` instead of `file`. That seems to solve the problem; however It does not close the files. — user8508033, Oct 05 '19 at 23:49

Use a with block

for filename in os.listdir():
    with open(filename, 'rb') as source:
        tmp = PdfFileReader(source)
        merger.append(tmp)
