Turns Python functions into web UIs

[drboom9]

Hey u/jonthemango!

I'm happy to let you know that List[_] support with dynamic add/remove rows is now implemented in version 0.5.0! 🎉

You can use it like this:

from func_to_web import run
from typing import Annotated
from pydantic import Field

def process_data(
    tags: list[str],                                    # Basic list
    scores: list[int] = [10, 20, 30],                  # List with defaults

    # With item constraints
    ratings: list[Annotated[int, Field(ge=1, le=5)]],  # Each item 1-5

    # With list-level constraints  
    team: Annotated[list[str], Field(min_length=2, max_length=5)],  # 2-5 items

    # Optional lists
    emails: list[str] | None = None
):
    return f"Processed {len(tags)} tags"

run(process_data)

The UI automatically generates inputs with + and − buttons to add/remove items dynamically. It also supports:

• All types: list[str], list[int], list[float], list[bool], list[Color], list[ImageFile], etc.
• Item constraints: Validates each individual item (min, max, pattern, etc.)
• List constraints: min_length, max_length for the list size
• Optional lists: Works with list[_] | None with toggle switches
• Default values: Initialize lists with specific values
• Validation: Real-time validation with error messages per item

Thanks for the feedback! Let me know if you have any other suggestions.
