Python 3.12.1 : Testing pypdf - version 4.1.0 .

I tried to find a solution for processing PDF files.
The newer Python package called "unstructured" I tested was a disaster and a waste of time and resources.
Today I will show you tests with the Python package called pypdf with version: 4.1.0.
You can find it on the official page.
Installation is simple with the pip tool and you can also add options offered by crypto.
pip install pypdf[crypto]

I create a little script for testing:
import os
from pypdf import PdfReader  
from pypdf import PdfWriter
#PdfMerger is deprecated and will be removed in pypdf 5.0.0. Use PdfWriter instead.
#from pypdf import PdfMerger

pdf_file = PdfReader("invoice-001.pdf")
print("Size in pages : ",len(pdf_file.pages))
print("========")
page = pdf_file .pages[0]
print("Page : ", page)
print("========")
text = page.extract_text()
print("Page text : ", text)
print("========")
print("PDF Metadata : ", pdf_file.metadata)
print("PDF Metadata - Title: ", pdf_file.metadata.title)
print("========")
pdf_writer = PdfWriter("invoice-002.pdf")
page = pdf_writer.add_blank_page(width=8.27 * 72, height=11.7 * 72)
pdf_writer.write("invoice-002.pdf")

from pypdf import PdfWriter

merger = PdfWriter()

for pdf in ["invoice-001.pdf", "invoice-002.pdf"]:
    merger.append(pdf)

merger.write("invoice-003.pdf")
merger.close()
The result is this:
python test_001.py
