Hi @meghanapuppala, thanks for getting in touch. I suspect you are using the Tobii Pro SDK Python Bindings?
I am afraid to inform you that this SDK only supports the Tobii Pro range of Eye Trackers.
If you wish to develop an interactive (or gaming) application with the Tobii 4C, then we would refer you to:
The Tobii Interaction Library @ https://developer.tobii.com/product-integration/interaction-library/
