The Jinja2 Template

26.4k

Jinja2 is a template engine for Python. It can be used as an alternative to the default Python string interpolation, which is the process of inserting data into strings. Jinja2 templates are easier to read and write than standard Python code, because they are written in a more natural language form.

Jinja2 supports many common programming concepts such as loops and conditionals. Jinja2 also provides an extensive list of filters that allow you to do things like formatting dates and times or generating random numbers.

inja2 templates are written in HTML or XML, and then converted to a bytecode format called “jinja” which can be evaluated by the Jinja environment (the jinja environment implements the language as an interpreter). The templates are converted to bytecode using the python compiler module, and then executed by an interpreter which parses and executes jinj scripts, which are compiled from templates written in HTML or XML.

Some of the most common uses of Jinja2 are:

  • Building web applications with Django
  • Generating HTML pages with Flask or Bottle
  • Generating emails with Mailgun or Mandrill
  • Building REST API endpoints with Flask or Django REST Framework

Jinja2 is a template engine for Python, which is often used with Django. Jinja templates are compiled to Python code before being executed. Jinja is the template engine for the Jinja2 templating language. It is not a standalone tool but rather a library of functions that can be used to extend another templating language, such as Jinja2.
