Python

Python has many HTTP libraries that are able to generate webhook requests. While there's no way to list all of them, here are some examples you can try.

httpx

The httpx client library can be used to submit both simple and more complex webhooks.

Send a payload as json

import httpx

response = httpx.post(
    "https://discord.com/api/webhooks/123/w3bh00k_t0k3n",
    json={
        "username": "Captain Hook",
        "content": "Ahoy matey! I be a webhook message!",
        # you can add embeds here, too
    }
)
# raise an exception if the operation failed.
response.raise_for_status()

Sending Attachments

import json
import httpx

with open("image.png", "rb") as io_object:
    response = httpx.post(
        "https://discord.com/api/webhooks/123/w3bh00k_t0k3n",
        data={"payload_json": json.dumps({
            "embeds": [{
                "title": "Hello, world!",
                "description": "This is a message with an image",
                "image": {"url": "attachment://filename"}
            }]
        })},
        files={"filetag": ("filename", io_object, "image/png")}
    )
    # raise an exception if the operation failed.
    response.raise_for_status()
