Explanation:

         This on_key_press function detects suspicious typing patterns, specifically monitoring for when the Tab key is pressed. If the Tab key is detected, it takes a screenshot and sends an alert email.

1. Monitor Key Presses:

   • The function is intended to be part of a keyboard event listener.

   • It triggers every time a key is pressed, with key being the key pressed.

2. Detect the Tab Key:

   • if key == keyboard.Key.tab:: Checks if the pressed key matches the Tab key, which is represented by keyboard.Key.tab in the pynput.keyboard module.

3. Respond to Tab Key Detection:

   • Logs the detection to the console: print("Tab detected during typing!").

   • Captures the current screen using the take_screenshot() function.

   • Sends an alert email via the send_email() function, including a predefined message and the screenshot as an attachment.

   • Deletes the screenshot file using os.remove(screenshot_path) to save disk space.

4. Error Handling:

   • Wraps the functionality in a try-except block to handle exceptions (e.g., issues with keyboard monitoring or the file system).

   • Prints an error message if an exception occurs.
