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])

使用Pypdf或其后续版本PyPDF2:

作为PDF工具包构建的Pure-Python库。它能够: 逐页拆分文档， 逐页合并文件，

(以及更多)

下面是一个适用于这两个版本的示例程序。

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")
