How can we extract the content of a PDF file using Python?

In Python, you can use the PyPDF2 library to extract content from PDF files. To start, you will need to install the PyPDF2 library by running the following command:

pip install PyPDF2

Then, you can utilize the following code to extract the content of the PDF file:

import PyPDF2

# 打开PDF文件
with open('example.pdf', 'rb') as file:
    # 创建一个PDF读取器对象
    pdf = PyPDF2.PdfFileReader(file)
    
    # 获取PDF文件的总页数
    num_pages = pdf.numPages
    
    # 循环遍历每一页
    for page in range(num_pages):
        # 获取当前页的内容
        page_content = pdf.getPage(page).extract_text()
        
        # 打印当前页的内容
        print(page_content)

Please note that the file example.pdf in the code above is the path to the PDF file from which you want to extract content. The code uses the PdfFileReader class to read the PDF file, uses the numPages attribute to get the total number of pages. Then, the getPage() method is used to get the content of a specific page, and the extract_text() method is used to extract the text content. Finally, you can use the print() function to print the extracted content.

I hope this helps you!
