Questions about TI 84 Plus CE-T Python Edition

You can use it in the classic way, but you also have the option of programming with Python. Python SDKs are available free of charge, my recommendation is Anaconda -> https://www.anaconda.com/products/individual

sorry, I don't know

The battery is available for approx. 25 Stutz (item 5600212).
