htpy is a library that makes writing HTML in plain Python fun and efficient, without a template language.
Define HTML in Python:
from htpy import body, h1, head, html, li, title, ul
menu = ["egg+bacon", "bacon+spam", "eggs+spam"]
print(
html[
head[title["Todays menu"]],
body[
h1["Menu"],
ul(".menu")[(li[item] for item in menu)],
],
]
)And get HTML:
<!DOCTYPE html>
<html>
<head>
<title>Todays menu</title>
</head>
<body>
<h1>Menu</h1>
<ul class="menu">
<li>egg+bacon</li>
<li>bacon+spam</li>
<li>eggs+spam</li>
</ul>
</body>

-
Leverage static types: Use mypy or pyright to type check your code.
-
Great debugging: Avoid cryptic stack traces from templates. Use your favorite Python debugger.
-
Easy to extend: There is no special way to define template tags/filters. Just call regular functions.
-
Works with existing Python web framework: Works great with Django, Flask or any other Python web framework!
-
Works great with htmx: htpy makes for a great experience when writing server rendered partials/components.
-
Create reusable components: Define components, snippets, complex layouts/pages as regular Python variables or functions.
-
Familiar concepts from React: React helped make it popular writing HTML with a programming language. htpy uses a lot of similar constructs.
htpy is available on PyPI. You may install the latest version using pip:
pip install htpy
