Using Python to split PDF files

This article mainly introduces how to split a PDF file in Python, and how to split a PDF file into a specified number of copies. It involves the use of the pyPdf module, for more information about how to use Python to split PDF files, see the following example. Share it with you for your reference. The details are as follows:

Use pyPdf to process PDF files
Split PDF files

Usage:
1) Place the file to be split in the input_dir directory.
2. Set the number of parts to be split in the configure.txt file (if you want to split four parts, set part_num = 4)
3) execute the program
4) The split file is saved in the output_dir directory.
The 5th runtime log is written in pp_log.txt.

P.S. This program can cut multiple PDF files in batches
