Implement batch segmentation of PDF files using Python

This article will introduce how to use Python to batch segment PDF files.

We will start with architecture design and gradually explain the process of code implementation to help readers quickly master this practical skill.

1. Architectural design

Before batch segmentation of PDF files, we need to design a reasonable architecture to ensure the maintainability and scalability of the code.

Here is a simple architectural design diagram:

1. Input module: Responsible for receiving the PDF file path and segmentation rules input by the user (such as splitting per page, splitting by page number, etc.).

2. Processing module: Responsible for reading PDF files and segmenting them according to the segmentation rules.

3. Output module: Save the split PDF file to the specified path.

2. Code implementation

Next, we will gradually implement each module in the above architecture.

First, we need to install a Python library for processing PDF files - PyPDF2.

You can use the following command to install:

pip install PyPDF2  

1. Input module

import os  
  
def get_pdf_files(directory):  
    pdf_files = []  
    for file in (directory):  
        if (".pdf"):  
            pdf_files.append((directory, file))  
    return pdf_files  
  
def get_split_rule():  
    # Obtain segmentation rules according to specific needs    pass  
  
def get_output_directory():  
    # Obtain the output path according to specific requirements    pass  

2. Processing module

from PyPDF2 import PdfFileReader, PdfFileWriter  
  
def split_pdf(file_path, split_rule):  
    pdf = PdfFileReader(file_path)  
    output_files = []  
    for i in range(()):  
        page = (i)  
        output_pdf = PdfFileWriter()  
        output_pdf.addPage(page)  
        output_file_path = f"{file_path}_{i}.pdf"  
        with open(output_file_path, "wb") as output_file:  
            output_pdf.write(output_file)  
        output_files.append(output_file_path)  
    return output_files  

3. Output module

def save_output_files(output_files, output_directory):  
    for file in output_files:  
        file_name = (file)  
        output_path = (output_directory, file_name)  
        (file, output_path)  

3. Batch split PDF files

Now, we can combine the above modules to realize the function of batch segmentation of PDF files.

def main():  
    directory = input("Please enter the directory where the PDF file is located:")  
    pdf_files = get_pdf_files(directory)  
    split_rule = get_split_rule()  
    output_directory = get_output_directory()  
  
    for file in pdf_files:  
        output_files = split_pdf(file, split_rule)  
        save_output_files(output_files, output_directory)  
  
    print("Split is complete!")  
  
if __name__ == "__main__":  
    main()  

4. Summary

This article introduces how to use Python to batch segment PDF files.

Through reasonable architecture design and code implementation, we can complete this task quickly and efficiently.

Readers can further optimize the code, add more functions, and implement more operations according to actual needs.
