Templating’ engine is an engine that can manipulate your HTML code from the server-side by using the server-side code. A template engine<\/strong> is quite popular in frameworks. In the template engine, we can replace variables with the values sent from the source and use it as an HTML file.<\/p>\n

Jinja is a popular template engine of the python programming language. Jinja is basically used by Flask as the templating engine.<\/p>\n

To install jinja –<\/h2>\n

pip install Jinja2<\/strong>

There are a few kinds of delimiters. The default Jinja delimiters are configured as follows:<\/p>\n

    \n
  1. \n{% … %} is used for Statements
    \nE.g. {% set text = \u2018Hello Word\u2019 %}\n<\/li>\n
  2. \n{{ … }} for Expressions to print the value.
    \nE.g. {{text}}\n<\/li>\n
  3. \n{# … #} are used for Comments which are not needed in template output
    \nE.g. {# This is an example of jinja template #}\n<\/li>\n
  4. \n# … ## for Line Statements
    \n# for item in seq:
    \n \u2026
    \n# endfor\n<\/li>\n<\/ol>\n
