如何使用python进行pdf文件分割

1.安装 PyPDF2 包

pip install PyPDF2

import PyPDF2

2.在 PyPDF2 库中，可以使用以下代码打开 PDF 文件：

?

1 2 3

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

?

1 2 3 4 5 6 7 8 9 10 11 12 13

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

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

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

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14

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)

6. 直接截至pdf中的某几页

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

from  PyPDF2 import PdfFileReader,PdfFileWriter   #用偏量实现纸质书页码向电子书页码的转换 offset  = 11 #纸质书页码范围 page_start = 10 page_end = 15 all_pdf = r"F:\工作\a.pdf" part_pdf = r"F:\工作\p.pdf" p_reader = PdfFileReader(all_pdf) p_writer = PdfFileWriter() for i in range(page_start + offset ,page_end + offset + 1):     p_writer.addPage(p_reader.getPage(i)) with open(part_pdf,'wb') as f:     p_writer.write(f)
