Nope. Python has been integrated only for scripting editor action, batch processing assets, etc. The same way is used in content creation apps or many other industries.
Many things can be done either with Python or blueprint editor utilities.
Python can’t be used for game scripting since its execution is extremely slow. It’s like 40 times slower than C++, seriously.
It’s perfect language for writing script-based tools and server tools. It wasn’t designed for scripting demanding realtime applications.
Nativized blueprints could be like 2-4x slower and this still you’d think about implementing a critical part of scripts in C++ (tick or any other frequent updates).
