- Upgrade Python version from 3.9 to 3.10 for virtual environment creation.
- Implement check for Python version availability before virtual environment setup.
- Add informative messages for successful virtual environment creation and activation instructions.
- Include guidance on installing dependencies after virtual environment activation.
