http://pieceofpy.com/2009/03/05/concatenating-pdf-with-python/提供了一个解决方案。

类似的:

from pyPdf import PdfFileWriter, PdfFileReader

def append_pdf(input,output):
    [output.addPage(input.getPage(page_num)) for page_num in range(input.numPages)]

output = PdfFileWriter()

append_pdf(PdfFileReader(file("C:\\sample.pdf","rb")),output)
append_pdf(PdfFileReader(file("c:\\sample1.pdf","rb")),output)
append_pdf(PdfFileReader(file("c:\\sample2.pdf","rb")),output)
append_pdf(PdfFileReader(file("c:\\sample3.pdf","rb")),output)

output.write(file("c:\\combined.pdf","wb"))

------ 11月25日更新------

------似乎以上代码不再工作------

------请使用以下:------

from PyPDF2 import PdfFileMerger, PdfFileReader
import os

merger = PdfFileMerger()

file_folder = "C:\\My Ducoments\\"

root, dirs, files = next(os.walk(file_folder))

for path, subdirs, files in os.walk(root):
    for f in files:
        if f.endswith(".pdf"):
            merger.append(file_folder + f)

merger.write(file_folder + "Economists-1.pdf")

它是可能的，使用Python，合并单独的PDF文件?

Yes.

下面的例子将一个文件夹中的所有文件合并为一个新的PDF文件:

#!/usr/bin/env python
# -*- coding: utf-8 -*-

from argparse import ArgumentParser
from glob import glob
from pyPdf import PdfFileReader, PdfFileWriter
import os

def merge(path, output_filename):
    output = PdfFileWriter()

    for pdffile in glob(path + os.sep + '*.pdf'):
        if pdffile == output_filename:
            continue
        print("Parse '%s'" % pdffile)
        document = PdfFileReader(open(pdffile, 'rb'))
        for i in range(document.getNumPages()):
            output.addPage(document.getPage(i))

    print("Start writing '%s'" % output_filename)
    with open(output_filename, "wb") as f:
        output.write(f)

if __name__ == "__main__":
    parser = ArgumentParser()

    # Add more options if you like
    parser.add_argument("-o", "--output",
                        dest="output_filename",
                        default="merged.pdf",
                        help="write merged PDF to FILE",
                        metavar="FILE")
    parser.add_argument("-p", "--path",
                        dest="path",
                        default=".",
                        help="path of source PDF files")

    args = parser.parse_args()
    merge(args.path, args.output_filename)

def pdf_merger(路径): """将pdf文件合并为一个pdf""" "

import logging
logging.basicConfig(filename = 'output.log', level = logging.DEBUG, format = '%(asctime)s %(levelname)s %(message)s' )

try:
    import glob, os
    import PyPDF2
    
    os.chdir(path)
    
    pdfs = []

        pdfs.append(file)
        
    if len(pdfs) == 0:
        logging.info("No pdf in the given directory")
        
    else:
        merger = PyPDF2.PdfFileMerger()
        
        for pdf in pdfs:
            merger.append(pdf)
            
        merger.write('result.pdf')
        merger.close()
        
except Exception as e:
    logging.error('Error has happened')
    logging.exception('Exception occured' + str(e))

pdfrw库可以很容易地做到这一点，假设您不需要保存书签和注释，并且您的pdf文件没有加密。Cat.py是一个示例拼接脚本，而子集.py是一个示例页面子集脚本。

串联脚本的相关部分——假设input是一个输入文件名列表，outfn是一个输出文件名:

from pdfrw import PdfReader, PdfWriter

writer = PdfWriter()
for inpfn in inputs:
    writer.addpages(PdfReader(inpfn).pages)
writer.write(outfn)

正如你所看到的，省略最后一页是很容易的，例如:

    writer.addpages(PdfReader(inpfn).pages[:-1])

免责声明:我是pdfrw的主要作者。

合并目录下的所有pdf文件

把pdf文件放到目录下。启动程序。你会得到一个合并了所有pdf文件的pdf。

import os
from PyPDF2 import PdfMerger

x = [a for a in os.listdir() if a.endswith(".pdf")]

merger = PdfMerger()

for pdf in x:
    merger.append(open(pdf, 'rb'))

with open("result.pdf", "wb") as fout:
    merger.write(fout)

今天我该如何编写上面相同的代码呢

from glob import glob
from PyPDF2 import PdfMerger



def pdf_merge():
    ''' Merges all the pdf files in current directory '''
    merger = PdfMerger()
    allpdfs = [a for a in glob("*.pdf")]
    [merger.append(pdf) for pdf in allpdfs]
    with open("Merged_pdfs.pdf", "wb") as new_file:
        merger.write(new_file)


if __name__ == "__main__":
    pdf_merge()
