Python脚本将PDF文件与空白页合并

Question

下面的脚本是根据其他人的建议编写的，但我似乎无法让它正常运行。我需要将几个3页的票据文件合并到一个文件中，以便打印，同时在每个票据文件之间添加一个空白页，以便每个账单正确打印(我们不希望在上一张账单的背面打印一张钞票的第一页)。

# If the file errors with "no module PyPDF2" then from command line, run pip install PyPDF2
import os
from os import listdir, mkdir, startfile
from os.path import isfile, join, exists
from PyPDF2 import PdfFileMerger, PdfFileReader, PdfFileWriter

#Input file path and print the pdf files in that path
path = input("Enter the folder location: ")
pdffiles = [f for f in listdir(path) if isfile(join(path, f)) and '.pdf' in f]
print('\nList of PDF Files:\n')
for file in pdffiles:
    print(file)

def add_blank_to_end(pdffiles: list) -> list:
    names = []
    for f in pdffiles:
        pdf_in = open(f, 'rb')
        pdf_file = PdfFileReader(pdf_in)
        output = PdfFileWriter()
        output.appendPagesFromReader(pdf_file)
        output.addBlankPage()
        names.append(f'b{f}')
        outputStream = open(f'b{f}', 'wb')
        output.write(outputStream)
    return names

#Append the pdf files
def merge_pdfs(pdffiles: list):
    merger = PdfFileMerger()
    for f in pdffiles:
        merger.append(f)
    merger.write("document-output.pdf")

with_blank = add_blank_to_end(pdffiles)
merge_pdfs(with_blank)
