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])

您可以从PyPDF2模块使用pdffilemerge。

例如，要从路径列表中合并多个PDF文件，可以使用以下函数:

from PyPDF2 import PdfFileMerger

# pass the path of the output final file.pdf and the list of paths
def merge_pdf(out_path: str, extracted_files: list [str]):
    merger   = PdfFileMerger()
    
    for pdf in extracted_files:
        merger.append(pdf)

    merger.write(out_path)
    merger.close()

merge_pdf('./final.pdf', extracted_files)

这个函数从父文件夹中递归地获取所有文件:

import os

# pass the path of the parent_folder
def fetch_all_files(parent_folder: str):
    target_files = []
    for path, subdirs, files in os.walk(parent_folder):
        for name in files:
            target_files.append(os.path.join(path, name))
    return target_files 

# get a list of all the paths of the pdf
extracted_files = fetch_all_files('./parent_folder')

最后，使用这两个函数进行声明。可以包含多个文档的parent_folder_path，以及用于合并PDF的目的地的output_pdf_path:

# get a list of all the paths of the pdf
parent_folder_path = './parent_folder'
outup_pdf_path     = './final.pdf'

extracted_files = fetch_all_files(parent_folder_path)
merge_pdf(outup_pdf_path, extracted_files)

你可以从这里获得完整的代码(来源):如何使用Python合并PDF文档

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)

使用字典以获得更大的灵活性(例如sort, dedup):

import os
from PyPDF2 import PdfFileMerger
# use dict to sort by filepath or filename
file_dict = {}
for subdir, dirs, files in os.walk("<dir>"):
    for file in files:
        filepath = subdir + os.sep + file
        # you can have multiple endswith
        if filepath.endswith((".pdf", ".PDF")):
            file_dict[file] = filepath
# use strict = False to ignore PdfReadError: Illegal character error
merger = PdfFileMerger(strict=False)

for k, v in file_dict.items():
    print(k, v)
    merger.append(v)

merger.write("combined_result.pdf")

from PyPDF2 import PdfFileMerger
import webbrowser
import os
dir_path = os.path.dirname(os.path.realpath(__file__))

def list_files(directory, extension):
    return (f for f in os.listdir(directory) if f.endswith('.' + extension))

pdfs = list_files(dir_path, "pdf")

merger = PdfFileMerger()

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

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

webbrowser.open_new('file://'+ dir_path + '/result.pdf')

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"))

------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")
