This Python scripts is designed to scrape a website for product information, specifically looking for items on discount. When a new discounted product is found, it sends a notification to a specified Telegram chat with details about the product, including its name, price, discount, and a link to the product.
There should be a file named sent_products.csv at the root of the project with the following header:
| Nome | Preço | Preço Antigo | Desconto | Link do Produto | Data |
|---|
The script reads configuration details from a .env file using the dotenv library. It expects the following parameters:
LINK_SITE: The URL of the website to scrape.TELEGRAM_TOKEN: Telegram Bot API token for authentication.CHAT_ID: The ID of the Telegram chat where notifications will be sent.
- The script uses a headless Chrome browser to perform web scraping without a visible browser window.

.envfile with the required configuration parameters. - Run the script:
poetry run python main.py.
To clean the CSV file:
- Execute o script:
poetry run python cleaning_csv.py.
This command will delete files that have been sent more than a week ago.
