Python Merge PDF files

This tutorial is intended to show you how to merge a list of PDF files into a single PDF using the Python programming language. 

We'll be using the PyPDF4 library for this purpose. PyPDF4 is a pure-python PDF library capable of splitting, merging together, cropping, and transforming the pages of PDF files.

Step 1:

Install PyPDF4

pip install PyPDF4

Step 2:

Below is just sample code for PDF file concatenation,

from PyPDF2 import PdfFileMerger

pdfs = ['file1.pdf', 'file2.pdf', 'file3.pdf', 'file4.pdf']

merger = PdfFileMerger()

for pdf in pdfs:
    merger.append(pdf)

merger.write("result.pdf")
merger.close()
