How to batch extract information from PDF using Python

To usepythonto batch extract information frompdf, you can use aPythonlibrary called PyPDF2. Here is a simple example to help you start extracting text information from PDF:

First, you need to install the PyPDF2 library. The library can be installed in a terminal or command prompt using the following command:

pip install PyPDF2

Then, you can use the following code to extract the text information in the PDF:

import PyPDF2 def extract_text_from_pdf(pdf_path): with open(pdf_path, 'rb') as file: pdf = PyPDF2.PdfFileReader(file) text = "" for page_number in range(pdf.getNumPages()): page = pdf.getPage(page_number) text += page.extractText() return text # 批量提取PDF中的文本信息 pdf_folder = "pdf文件夹路径" output_folder = "输出文件夹路径" import os for filename in os.listdir(pdf_folder): if filename.endswith(".pdf"): pdf_path = os.path.join(pdf_folder, filename) text = extract_text_from_pdf(pdf_path) output_path = os.path.join(output_folder, f"{filename}.txt") with open(output_path, 'w', encoding='utf-8') as file: file.write(text)

In the above code,pdf_folderis the path to the folder containing the PDF file, andoutput_folderis the path to the folder to which the extracted text will be output. The code will loop through all PDF files in the folder, extract the text content of each file, and save the extracted text to the corresponding text file.

Please note that this code can only extract plain text information in PDF. If the PDF contains non-text content such as images or tables, the code may not be able to extract it or extract it correctly.
