"""
This script modifies the Windows registry to toggle Developer Mode on or off.
It checks if the registry key exists and creates it if not.
Then, it prompts the user to enable or disable Developer Mode & modifies the registry accordingly.
Error messages are displayed if any issues arise.

Requirements:
- Python 3.x
- Windows 10+

Functions:
- check_registry_key(key_path) : Checks if the specified registry key exists.
- create_registry_key(key_path): Creates the specified registry key.
- toggle_developer_mode(enable): Toggles Developer Mode on or off by setting a registry value.

Usage:
1. Run the script using Python 3.x.
2. Follow the on-screen prompts to enable or disable Developer Mode.
3. Verify the registry for the changes.

Additional Notes:
- This script modifies the Windows registry, but should not require administrator privileges.
- Use caution when modifying the registry, as incorrect changes can cause system instability.
- Compatible with Windows 10+ operating systems.
