How to create PDF files in Python

How to create PDF files in Python

You can create PDF files in Python using various libraries. One of the most popular libraries for creating PDF files is reportlab. Here's a basic example of how to create a PDF file using reportlab:

  1. First, make sure you have reportlab installed. You can install it via pip:
pip install reportlab
  1. Once installed, you can use the following code to create a simple PDF file:
from reportlab.lib.pagesizes import letter from reportlab.pdfgen import canvas def create_pdf(filename): # Create a canvas c = canvas.Canvas(filename, pagesize=letter) # Set font and size c.setFont("Helvetica", 12) # Write some text text = "Hello, this is a PDF generated using reportlab!" c.drawString(100, 750, text) # Draw a rectangle c.rect(100, 700, 400, 100) # Save the PDF c.save() if __name__ == "__main__": create_pdf("example.pdf")

This code creates a PDF file named example.pdf with some text and a rectangle drawn on it.

  1. Run the script, and it will generate the PDF file in the current directory.

This is just a basic example to get you started. reportlab offers many more features for creating complex PDF documents, such as adding images, tables, charts, and more. You can refer to the reportlab documentation for more advanced usage.
