python - 合并两个 PDF

Question

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 pdf 添加封面和包含页码的页脚，修复了一些东西，现在我最后一次运行它以查看它是否正常工作，它花费了太多时间，没有错误，确实我做错了什么，或者合并和添加页脚需要那么长时间吗？我正在处理 3 个文件，它转换它们的速度非常快。

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，我认为问题出在这里

   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'))

因为我正在尝试将 position=0 与 position=0 合并，所以不确定

这实际上作为评论更好，但我想展示代码。您需要在其中添加一些 try block 以捕获任何错误 - 这是您可以做的非常基本的事情。

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)
