This article will use IronPDF for Python to create simple PDF documents from templates.

IronPDF for Python

IronPDF is a powerful Python library that revolutionizes the way developers interact with PDF documents. Designed to simplify the creation, editing, and manipulation of PDF files, IronPDF empowers Python programmers to effortlessly integrate sophisticated PDF functionalities into their applications. Whether it's generating PDFs from scratch, converting HTML content into high-quality PDFs, or merging, splitting, and editing existing PDFs, IronPDF's comprehensive set of tools and APIs offer an intuitive and efficient solution. With its user-friendly interface and extensive documentation, IronPDF opens up a world of possibilities for developers seeking to harness the full potential of PDFs in their Python projects, making it an invaluable asset in the realm of document management and automation.

Prerequisites

Generating a PDF from a template in Python requires the following prerequisites to be in place:

  1. Python Installation: Ensure that you have Python installed on your system. The IronPDF library is compatible with Python 3.0 or above versions, so make sure you have a compatible Python installation.
  2. .NET 6.0 SDK: The .NET 6.0 SDK is a prerequisite for utilizing the IronPDF library in Python. IronPDF is built on top of the .NET Framework, which provides the underlying capabilities required for PDF generation and manipulation. Therefore, .NET 6.0 SDK must be installed to use IronPDF in Python.

  3. IronPDF Library: To install the IronPDF library, use pip, the Python package manager. Open your command-line interface and execute the following command:

    pip install ironpdf
    pip install ironpdf
    SHELL
  4. Integrated Development Environment (IDE): While not strictly necessary, using an IDE can greatly enhance your development experience. It offers features like code completion, debugging, and a more streamlined workflow. One popular IDE for Python development is PyCharm. You can download and install PyCharm from the JetBrains website at https://www.jetbrains.com/pycharm/.

Creating a New Python Project

Here are the steps to create a new Python Project in PyCharm.

  1. To create a new Python project open PyCharm, go to "File" in the top menu and click on "New Project".

Generate PDF files from Template using IronPDF

This section will explain how to generate PDF documents from HTML templates using input data from the console to create PDF files.

Firstly, import some dependencies for creating PDF files.

# Import the required classes from the libraries
from ironpdf import ChromePdfRenderer
from jinja2 import Template
# Import the required classes from the libraries
from ironpdf import ChromePdfRenderer
from jinja2 import Template
PYTHON

Next, declare renderer as a ChromePdfRenderer object and use it to render HTML templates.

# Create a renderer object to generate PDFs
renderer = ChromePdfRenderer()
# Create a renderer object to generate PDFs
renderer = ChromePdfRenderer()
PYTHON

Now, create an HTML template document for reusable purposes to create PDF files. Just create a new variable and populate it with HTML content containing placeholders.

# Define an HTML template with placeholders for dynamic data
html_template = """
<!DOCTYPE html>
<html>
<head>
    <title>{{ title }}</title>
</head>
<body>
    <h1>{{ title }}</h1>
    <p>
        Hello, {{ name }}! This is a sample PDF generated from a template using IronPDF for Python.
    </p>
    <p>
        Your age is {{ age }} and your occupation is {{ occupation }}.
    </p>
</body>
</html>
"""
# Define an HTML template with placeholders for dynamic data
html_template = """
<!DOCTYPE html>
<html>
<head>
    <title>{{ title }}</title>
</head>
<body>
    <h1>{{ title }}</h1>
    <p>
        Hello, {{ name }}! This is a sample PDF generated from a template using IronPDF for Python.
    </p>
    <p>
        Your age is {{ age }} and your occupation is {{ occupation }}.
    </p>
</body>
</html>
"""
PYTHON

With the design template ready, write code that will take input from the user and store it in a dictionary.

# Gather input from the user
title = input("Enter the title: ")
name = input("Enter your name: ")
age = input("Enter your age: ")
occupation = input("Enter your occupation: ")

# Store the input data into a dictionary for rendering the template
data = {
    "title": title,
    "name": name,
    "age": age,
    "occupation": occupation
}
# Gather input from the user
title = input("Enter the title: ")
name = input("Enter your name: ")
age = input("Enter your age: ")
occupation = input("Enter your occupation: ")

# Store the input data into a dictionary for rendering the template
data = {
    "title": title,
    "name": name,
    "age": age,
    "occupation": occupation
}
PYTHON

Further, the code below will integrate the data into the template document and render HTML templates using the IronPDF renderer object created earlier. Finally, save the PDF file using the SaveAs method.

# Create a Template object with the HTML structure
template = Template(html_template)

# Render the template with the user-provided data
html_content = template.render(**data)

# Generate the PDF from the rendered HTML content
pdf = renderer.RenderHtmlAsPdf(html_content)

# Save the generated PDF to a file
pdf.SaveAs("output.pdf")
# Create a Template object with the HTML structure
template = Template(html_template)

# Render the template with the user-provided data
html_content = template.render(**data)

# Generate the PDF from the rendered HTML content
pdf = renderer.RenderHtmlAsPdf(html_content)

# Save the generated PDF to a file
pdf.SaveAs("output.pdf")
PYTHON

With that, the code to create PDF files dynamically is completed. Let's run the code to see the output.

Output Example 1

After running the code, it will ask for the following inputs from the user.

Enter the inputs one by one and press enter after each input. Once all four inputs are entered, it will generate a PDF file.

Output Example 2

Now, rerun the program and try different inputs.

As you can see below, the output file format is the same, but it is updated with the new inputs.
