I have been working on where I create a payload of dicts with different values as store, name etc etc which you will see very soon. The idea is that with the payload I send to this script, it should see if the values is in the payload (dict) and if it is then add it into discord embed. As simple as it sounds.

I have done something like this:

#!/usr/bin/python3
# -*- coding: utf-8 -*-
import time
from threading import Thread
from typing import Dict

import pendulum
from discord_webhook import DiscordEmbed, DiscordWebhook
from loguru import logger

mixed_filtered = {
    'test1': 'https://discordapp.com/api/webhooks/529345345345345/6h4_yshmNDKktdT-0VevOhqdXG9rDhRWclIfDD4jY8IbdCQ5-kllob-k1251252151',

}

mixed_unfiltered = {
    'test1': 'https://discordapp.com/api/webhooks/12412421412412/6h4_yshmNDKktdT-0VevOhqdXG9rDhR12412412414Q5-kllob-kI2jAxCZ5PdIn',

The mock data is at the very bottom but in the future I will instead send the payload to the function.

I wonder what can I do to try to have less code but that still does the job. I feel like there should be a way more cleaner way to do this than what I did but looking forward to see what can be improved :)

Let me know if there is any missing information. The script should be runnable by copy pasting it but make sure to create your own discord webhooks to test the embed. I will unfortunately need to modify them so no one can spam me :)

If I were a smart man I'd give up on recommending that you stop using a payload dictionary for internal data representation and instead use classes, but I'm not a smart man. Please. I implore you. We're not in JavaScript - objects don't have to be dictionaries. This could be well-represented by a class for product, and a class for product size.

Otherwise:

if payload.get("price") should be replaced by if 'price' in payload if it were only that statement; but since you actually use it,

if payload.get("price"):
    embed.add_embed_field(
        name="Price",
        value=payload["price"]
    )

should become

price = payload.get('price')
if price is not None:
    embed.add_embed_field(name='Price', value=price)

More broadly: your create_embed is a presentation function but mixes in logic concerns such as stock summation, and store-specific logic (i.e. Footlocker). That should be separated.

Your

# FIXME Add discord notficiation and raise exception

first of all has a typo - notficiation -> notification - and second of all, while this is waiting to be fixed it's of crucial importance that you not swallow exceptions. Part of development and debugging is seeing errors, and your code breaks that. So replace your pass with a raise in the meantime.

  • \$\begingroup\$ Hi again! :) Regarding the payload being dictionary it is something that I still have issue with and it is something we have worked on together as you remember :) My problem is that I do not know how I can work with only classes where I have previously asked for a code review regarding the part where I actually send the payload to the create_embed which can be found from here codereview.stackexchange.com/q/259867/223687 - If I could get more description over how I can actually do a comparision with just classes and throw away the dicts. That would be very cool to know how \$\endgroup\$

I did realize that I have done something more complicated and harder to read, thanks for that :) Will work on that part but now im more concern if im going to change with classes then I most likely wont need the dicts at all.
