如何使用python进行pdf文件分割

1.安装 PyPDF2 包

pip install PyPDF2

然后
import PyPDF2

2.在 PyPDF2 库中，可以使用以下代码打开 PDF 文件：

pdf_file = open('filename.pdf', 'rb')
pdf_reader = PyPDF2.PdfFileReader(pdf_file)
total_pages = pdf_reader.numPages

3.下面代码将每一页分开

from  PyPDF2 import PdfFileReader,PdfFileWriter

pdf_path = r"F:\工作\1.pdf"
save_path = r"F:\工作\a\a"
# Split Pages of PDF
pdf_reader = PdfFileReader(pdf_path)
for i in range(0,pdf_reader.getNumPages()):
    pdf_writer = PdfFileWriter()
    pdf_writer.addPage(pdf_reader.getPage(i))
    # Every page write to a path
    with open(save_path+'{}.pdf'.format(str(i)), 'wb') as fh:
        pdf_writer.write(fh)
    print('{} Save Sucessfully !\n'.format(str(i)))

4.　　2个PDF 文件合并为1个

from  PyPDF2 import PdfFileReader,PdfFileWriter

merge_pdf = r"F:\工作\z.pdf"
p1_pdf = r"F:\工作\a\a0.pdf"
p2_pdf = r"F:\工作\a\a1.pdf"

p1_reader = PdfFileReader(p1_pdf)
p2_reader = PdfFileReader(p2_pdf)

merge = PdfFileWriter()
# Write p1
for i in range(0,p1_reader.getNumPages()):
    merge.addPage(p1_reader.getPage(i))
# Write p2
for j in range(0,p2_reader.getNumPages()):
    merge.addPage(p2_reader.getPage(j))
# Write out
with open(merge_pdf,'wb') as f:
    merge.write(f)

5.将多个单页合并成一页

from  PyPDF2 import PdfFileReader,PdfFileWriter

merge_pdf = r"F:\工作\z.pdf"
p_pdf = r"F:\工作\a\a"

merge = PdfFileWriter()

for i in range(220,227):
    p_reader = PdfFileReader(p_pdf + str(i) +'.pdf')
    for i in range(0,p_reader.getNumPages()):
        merge.addPage(p_reader.getPage(i))
# Write out
with open(merge_pdf,'wb') as f:
    merge.write(f)

　　不知道为什么，直接从原PDF文档中截取某几页的代码总是不正常。只好采用以上分步执行的办法。
