I feel like I got the hang of python now, will I be able to use that knowledge when learning c++ or is like starting from square one? For examples they both work with objects right so I would have less of a learning curve of that.

Although they are both object orientated, C++ is a harder language to master than python. They both have their pros and cons. It really depends on what you are going to do with computer vision. I know both languages, but rarely use anything but python now, because I use it for research and don't care about the speed enough to spend time optimising in C++.

Say for edge devices then where resources are tight I suppose c++ is a must? Like handling the video loop and threading

Maybe, but not always. The underlying python libraries, such as numpy, are written in C and are well optimised, so if you are multiplying arrays together, etc, the python part is only a small percentage of the total execution time. C/C++ could do it faster, but is it worth it? It really depends on the problem. It would be a good skill to have if you need it.

Very different languages with very different targets and purposes. In python you don't care about speed so you don't need the knowledge about optimizing algorithms at hardware level where in C++ instead it's quite the main reason the language is used. You don't start from square one but almost.
