No.
I will answer the actual question being asked in the title.
No to both. I consider them both to be almost a waste of my time. I have rarely seen enough value to phthon or react to get me to use them. I consider them lazy code. I used to do that type of coding a lot. I was afraid of learning C++ (as developed by Stroustrup) because it looked so complicated. But, I did learn it (some). Now I almost exclusively use C++11. No python. No react. etc. Sometimes, rarely, I still use javascript, and write some server side scripts etc., and a little CLI. But not much these days. For your answer, "No."
I suggest that you get away from python and find another way of doing what your are doing. You might be limiting yourself so much that it costs your company too much financially to do what you want with python.
