Can you write functions and classes in Python that roughly mimic the DSL you're aiming for? This is often called an embedded DSL, and it's a great technique for allowing developers to work with domain objects inside a language that they're still familiar with.

There's a handful of templating languages that do this sort of thing using functions, so in Python you might write

    form(
        {"method": "POST"},
        label(
            "Name",
            input({"type": "text"}),
        ),
    )

The learning curve becomes significantly lighter because you're just using Python constructs in the Python language, which means your IDE can suggest functions to you like it would with any other library.
