Specify Python type scenarios on a function

Question

I would like to have a mypy-accepted constructor, based on this example:

N = Union[Network4, Network6]
A = Union[Address4, Address6]

class Foo:
    def __init__(self, network: N, address: A) -> None:
        self.network: N = network
        self.address: A = address

As you see in this example, you can mix the IPv4 and IPv6 in one call, but I want to accept the appropriate pairs only.

Can I, and how can I describe that with pure type-hinting (without @overload)?

From looking at your indextest.html file it seems like you're missing attribute(s) in your link tag.

Try replacing your link tag with this:

<link rel="stylesheet" type="text/css" href="https://cdnjs.cloudflare.com/ajax/libs/slick-carousel/1.6.0/slick.min.css"/>

Based on the error message its saying that react-slick is not installed or probably not imported correctly. From looking at your Slider.js file, I'm not sure how your codes are being structured but it seems like you're missing several imports:

import React from "react";
import ReactDOM from "react-dom";
import Slider from "react-slick";

For a clearer guide you can try following the steps in their documentation: quick-start guide from react-slick.
