HTML Template - HTML

HTML Template is a library that allows programmers to generate HTML code dynamically using Python. It provides a simple and straightforward way to create HTML documents without writing the code manually.

Features

HTML Template offers a set of features that simplify the process of generating HTML code. Here are some of the main features:

  • Easy HTML syntax: HTML Template uses a syntax that's similar to HTML for creating dynamic pages.
  • Automatic escaping: HTML Template automatically escapes special characters like angle brackets and ampersands, making your code more secure.
  • Template inheritance: You can create parent templates that define a basic HTML structure, and child templates that inherit from the parent and add the specific content.
  • Loops and conditionals: HTML Template provides loops and conditionals, which can be used to generate repeated or conditional HTML code.
  • Macros: You can define macros that can be reused across multiple pages.
Getting Started

To get started with HTML Template, you need to install it first. You can install it using pip:

pip install html-template

Once you have installed HTML Template, you can start using it in your Python code. Here's a simple example:

from html_template import HTML

page = HTML()
page.p('Hello, world!')
print(page.render())

This code generates a simple HTML document with a paragraph that says "Hello, world!". The HTML() function creates a new HTML document, and the p() method adds a paragraph element to the document. Finally, the render() method generates the HTML code as a string.

Template Inheritance

One of the most powerful features of HTML Template is template inheritance. With template inheritance, you can create a basic HTML structure that can be reused across multiple pages.

Here's an example of a parent template:

<!DOCTYPE html>
<html>
<head>
  <meta charset="UTF-8">
  <title>{% block title %}{% endblock %}</title>
</head>
<body>
  <header>
    <h1>{% block heading %}{% endblock %}</h1>
  </header>
  <main>
    {% block content %}{% endblock %}
  </main>
  <footer>
    {% block footer %}{% endblock %}
  </footer>
</body>
</html>

This template defines a basic HTML structure, with a header, a main section, and a footer. The {% block %} tags define sections that can be overridden in child templates.

Here's an example of a child template that inherits from the parent:

{% extends "parent.html" %}

{% block title %}My Page{% endblock %}

{% block heading %}My Page{% endblock %}

{% block content %}
  <p>This is my page!</p>
{% endblock %}

{% block footer %}
  <p>Copyright &copy; 2021</p>
{% endblock %}

This template extends the parent template using the {% extends %} tag. It overrides the title, heading, content, and footer blocks to create a specific page.

Conclusion

HTML Template is a powerful library that simplifies the process of generating HTML code. It provides a simple and easy-to-use syntax, automatic escaping, template inheritance, loops and conditionals, and macros. If you need to generate HTML code from Python, HTML Template is definitely worth checking out!
