Notes

• The script is set up to use a specific Google Sheet and range. This can be adjusted in the code as necessary.
• The script is set up to run after every draw of the lottery, which occurs three times a week: using GitHub Actions and cron the script is set to run at a specified time, ensuring that the data in the spreadsheet is always up to date.
• The script is set up to run in headless mode, meaning that the Chrome window will not be visible. This can be adjusted in the code as necessary.
• Detailed error messages are logged to app.log using Python's built-in logging module for improved error reporting and debugging.
• The script gracefully handles exceptions during web scraping and Google Sheets update operations, ensuring robustness and reliability.
