HTML in Python

work-in-progress
contributions appreciated

pyxy lets you put HTML directly in Python code. You can think of it as JSX for Python. It builds on the fantastic work of pyxl, which is a similar project predating JSX. Compared to pyxl, it takes a new approach that makes other tools do most of the work:

parso provides the tokenization and parsing, using a custom grammar to enable handling XML
htpy is used to rebuild markup

Here's a minimal example:

def is_logged_in() -> bool:
    return False

animal_images = ["cat.png", "dog.png", "cow.png"]
status_image = "logged-in.png" if is_logged_in() else "logged-out.png"

def demo():
    return (
        <div>
            <img src={status_image} />
            <ul>
                { <li><img src={image_file} /></li> for image_file in animal_images }
            </ul>
        </div>
    )

print(demo())

<div><img src="logged-out.png"><ul><li><img src="cat.png"></li><li><img src="dog.png"></li><li><img src="cow.png"></li></ul></div>
