import PyPDF2 
import glob
import os
from fpdf import FPDF
import shutil

class MyPDF(FPDF): # adding a footer, containing the page number
    def footer (self):
        self.set_y(-15)
        self.set_font("Arial", Style="I", size=8)
        pageNum = "page %s/{nb}" % self.page_no()
        self.cell(0,10, pageNum, align="C")


if __name__ == "__main__":
    os.chdir("pathtolocation/docs/") # docs location
    os.system("libreoffice --headless --invisible --convert-to pdf *") # this converts everything to pdf
    for file in glob.glob("*"):
        if file not in glob.glob("*.pdf"):
            shutil.move(file,"/newlocation") # moving files we don't need to another folder

    # adding the cover and footer
    path = open(file, 'wb')
    path2 = open ('/pathtocover/cover.pdf')
    merger = PyPDF2.PdfFileMerger()
    pdf = MyPDF()

    for file in glob.glob("*.pdf"):
        pdf.footer()
        merger.merge(position=0, fileobj=path2)
        merger.merge(position=0, fileobj=path)
        merger.write(open(file, 'wb'))

此脚本转换为pdf，为包含页码的pdf和页脚添加封面，修复了一些内容，现在我最后一次运行它以查看它是否有效，它正在服用太多时间，没有错误，我做错了什么或者需要那么长时间来合并和添加页脚？我正在处理3个文件，并且转换速度非常快。

异常输出

convert /home/projects/convert-pdf/docs/sample (1).doc ->
/home/projects/convert-pdf/docs/sample (1).pdf using writer_pdf_Export

所以它正在转换和移动，我认为这个问题就在这里

   for file in glob.glob("*.pdf"):
        pdf.footer()
        merger.merge(position=0, fileobj=path2)
        merger.merge(position=0, fileobj=path)
        merger.write(open(file, 'wb'))

由于我尝试将position=0与position=0合并，但不确定

这实际上更好的评论，但我想显示代码。你需要在那里添加一些try块来捕捉任何错误 - 这是你所做的超级基础。

import PyPDF2 
import glob
import os
from fpdf import FPDF
import shutil

class MyPDF(FPDF): # adding a footer, containing the page number
    def footer (self):
      try:
        self.set_y(-15)
        self.set_font("Arial", Style="I", size=8)
        pageNum = "page %s/{nb}" % self.page_no()
        self.cell(0,10, pageNum, align="C")
      except Exception, err:
        print "Error applying footer: {}".format(err)


if __name__ == "__main__":

  try:
    os.chdir("pathtolocation/docs/") # docs location
    os.system("libreoffice --headless --invisible --convert-to pdf *") # this converts everything to pdf
    for file in glob.glob("*"):
        if file not in glob.glob("*.pdf"):
            shutil.move(file,"/newlocation") # moving files we don't need to another folder

    # adding the cover and footer
    path = open(file, 'wb')
    path2 = open ('/pathtocover/cover.pdf')
    merger = PyPDF2.PdfFileMerger()
    pdf = MyPDF()
  except Exception, err:
    print "error setting up the pdf: {}".format(err)

    for file in glob.glob("*.pdf"):
      try:
        pdf.footer()
        merger.merge(position=0, fileobj=path2)
        merger.merge(position=0, fileobj=path)
        merger.write(open(file, 'wb'))
      except Exception, err:
        print "Error processing glob: {}".format(err)

合并两个PDF
