What are some simple project ideas using C++ and Python?

I think it could be useful to create a C++ project. C++ is more focused on development, while Python is great for scripting and configuration. If your Python project grows too much, it could get complicated with all the libraries you might need to incorporate. Keeping it simple with C++ might be a better route for now.

How about making a weather application in UE5? You could pull data from several sources like weather stations or services like NOAA. Even if it ends up being a bit of a toy, as long as you find it fun and functional, that's what counts! Also, consider diving into modding existing games made with UE—it provides a structured environment for experimenting and learning.

When learning UE5, I don't think there's much chance of forgetting C++. You can write efficient C++ systems that interact nicely with the engine. But if you're looking specifically for cross-language projects, a Python library that performs intensive computation, like NumPy, could be an interesting challenge!
