Building a Web Scraper to Track Product Prices and Send Alerts

I listed a gig offering custom web scraping scripts on Fiverr and Upwork. Within a week, I got my first few clients, each paying $50-$200 per script. The demand was bigger than I expected.

Instead of writing custom scripts for every client, I made a generic scraper that could handle multiple websites. I put it up for sale on Gumroad and Sellix for $19.99, and people started buying it.

# قاعدة بيانات للأسئلة والردود
qa_pairs = {
    "مرحبا": "أهلاً وسهلاً! كيف يمكنني مساعدتك اليوم؟",
    "كيف حالك؟": "أنا مجرد روبوت، لكنني بخير إذا كنت بخير!",
    "ما هو اسمك؟": "أنا روبوت دردشة بسيط. اسألني أي شيء!",
    "وداعاً": "وداعاً! أتمنى لك يوماً سعيداً."
}

لنجعل روبوت الدردشة أكثر ذكاءً باستخدام تقنية lemmatization لفهم النصوص:

We’ll use the websockets library to handle communication between players.

import asyncio
import websockets
import json

game = TicTacToe()
players = []

async def handler(websocket, path):
    global players
    players.append(websocket)
    try:
        async for message in websocket:
            data = json.loads(message)
            if "move" in data:
                position = data["move"]
                response = game.make_move(position)
                for player in players:
                    await player.send(json.dumps({"board": game.board, "status": response}))
    except websockets.ConnectionClosed:
        players.remove(websocket)

start_server = websockets.serve(handler, "localhost", 8765)

asyncio.get_event_loop().run_until_complete(start_server)
asyncio.get_event_loop().run_forever()

Set up speech recognition to capture voice commands using your microphone.

import speech_recognition as sr

def listen_command():
    recognizer = sr.Recognizer()
    with sr.Microphone() as source:
        print("Listening...")
        try:
            audio = recognizer.listen(source)
            command = recognizer.recognize_google(audio)
            print(f"You said: {command}")
            return command.lower()
        except sr.UnknownValueError:
            print("Sorry, I didn't catch that.")
            return None
