Python 3 - 拆分 PDF 文件

Question

我希望从我的 PDF 文件中提取第 30 到 34 页并将其制成一个文档。但是，我的代码似乎只能让我进入第 34 页。

import os
from PyPDF2 import PdfFileReader, PdfFileWriter

path = 'file_path'

pdf = PdfFileReader(path, "rb")

for page in range(29, 33):
    pdf_writer = PdfFileWriter()
    pdf_writer.addPage(pdf.getPage(page))

output_fname = "Output.pdf"

with open(output_fname, 'wb') as out:
    pdf_writer.write(out)

print ("PDF file has been split")

好的，我注意到如果我更改了代码的中间部分以手动添加页面，它就可以工作。但我确实需要一种不那么笨重的方法来提取大量页面。

output.addPage(pdf.getPage(29))
output.addPage(pdf.getPage(30))

Answer 1

Nvm 我意识到我的错误。应该刚刚从循环语句中排除 pdf_writer = PdfFileWriter()。

import os
from PyPDF2 import PdfFileReader, PdfFileWriter

path = 'file_path'
pdf = PdfFileReader(path, "rb")

pdf_writer = PdfFileWriter()

for page in range(29, 33):
    pdf_writer.addPage(pdf.getPage(page))

output_fname = "Output.pdf"

with open(output_fname, 'wb') as out:
    pdf_writer.write(out)

print ("PDF file has been split")

Answer 2

import os
from PyPDF2 import PdfFileReader, PdfFileWriter

path = r"C:\Users\scriptdocuchm_ktm.pdf"

pdf = PdfFileReader(path, "rb")
pdflist = []
pdf_writer = PdfFileWriter()

for page in range(66,70):
    pdflist.append(page)
    pdf_writer.addPage(pdf.getPage(page))

print(pdflist)

output_filename = "split.pdf"

with open(output_filename, 'wb') as out:
    pdf_writer.write(out)

print ("pdf file has been split")
