Then in this file, simply add one line: Your name is: is now equal to “Mark”. All you have to do it create a text file (let’s call it name.txt). This template will simply be a text file that prints out the value of a name. Let’s create a simple template just as an illustration.

Writing the python code that assigns the placeholder values to your Jinja2 templates and renders a new text string according to these values.

In these templates, you can use a variety of Jinja2 syntax features that allow you to adjust the look of the file and how it loads the placeholder data.

Creating the text file Jinja2 templates that contain placeholder values.

There are two main components of working with Jinja2: Keep in mind that Jinja2 can come in handy for other reporting applications, like sending automated emails or creating reports in other text file formats. We’ll be using Jinja2 to generate HTML files of our reports that we will convert into PDFs with other tools. It’s a very flexible tool, used widely in Python web applications to generate HTML for users. You can think of it like super high-powered string substitution. In short, it lets you automatically generate text documents by programmatically filling in placeholder values that you assign to text file templates. Jinja2 is a great tool to become familiar with, especially if you do web development in Python.

Then follow instructions here to install wkhtmltopdf. We’ll install our required packages with the following commands: You also need to install a tool called wkhtmltopdf for pdfkit to work.Pdfkit to convert these reports to PDF.Jinja2 templates to generate HTML files of the reports that I need.The particular solution I came up with uses two main tools:

I recently needed to do PDF reporting in a work assignment. This is often important for getting buy-in from people comfortable with the old system. This means that if the legacy system used PDF reporting, then you should strongly consider creating this functionality in the replacement system.

You need to match existing reporting formats : If you’re replacing a legacy reporting system, it’s often a good idea to try to match existing reporting methods as your first step.

People often want “hard copies” of particular reports they are running and don’t want to reproduce everything they did in an interactive dashboard.

You need to make reports that are easily printable.

This seems somewhat “old school” nowadays, but here are a couple situations why you might want to consider it: Once in a while as a data scientist, you may need to create PDF reports of your analyses.
