[907] Merge multiple PDF files into one in Python

You can merge multiple PDF files into one using various Python libraries. One common approach is to use the PyPDF2 library, which allows you to manipulate PDF files. Here's a step-by-step guide to merging multiple PDFs into one using PyPDF2:

1. First, install the PyPDF2 library if you haven't already. You can install it using pip:

   pip install pyinstaller

2. Create a Python script to merge the PDFs:

   import PyPDF2
    
   # List of PDF files to merge
   pdf_files = ["file1.pdf", "file2.pdf", "file3.pdf"]
    
   # Create a PDF merger object
   pdf_merger = PyPDF2.PdfFileMerger()
    
   # Iterate through the list of PDF files and append them to the merger
   for pdf_file in pdf_files:
       pdf_merger.append(pdf_file)
    
   # Output file name for the merged PDF
   output_file = "merged.pdf"
    
   # Write the merged PDF to the output file
   with open(output_file, "wb") as output:
       pdf_merger.write(output)
    
   # Close the PDF merger object
   pdf_merger.close()

   In this example, you provide a list of PDF files to merge, iterate through the list, and append each file to the pdf_merger object. Finally, you write the merged PDF to an output file.

3. Run the script, and the merged PDF will be created in the current working directory with the name "merged.pdf."

Remember to provide the correct file paths for the PDFs you want to merge in the pdf_files list. You can adjust the script to include more files as needed.

This is a basic example of merging PDFs with PyPDF2. Depending on your needs, you can customize the script to handle additional operations, such as rotating pages, reordering pages, and more.
