Hello there!!

I hope you are doing well. So here is my answer, in my 11th class I studied computer science as my main paper in that I brushed up my skills in C and C++, and when I was in my first year I had to pik up on python, it was very easy for me to study python compared to the students who knew nothing of coding so I can surely say yes u will pik the language up must faster. C or your c++ is the very first fundamental language based on this other language are build up so learning C or C++ is very beneficial. With only C u can pik up on any computer languages very easily. C++ is like a subset of C so knowing any 1 is okay.

Now for machine learning a little bit of coding skills is enough, but it's better to have knowledge of data structures, algorithms, and OOPs concept and guess what your C++ deals with this all !!

Hope this helps !!

Now a days , lot of people are shifting everyday to python. Due to the advancement in the industry of computation and data science as well as data mining , python is playing an important role.  So if you want to do significant work in this industry then I would suggest you to move to python. Python is a easy but a vital language that can perform a lot of tasks despite of its simple sintax. So as you have a programming experience in c++ then you will be easily able to coup it up in 2-3 months with adequate practice.

Learning python will help you in a number of ways in the field of Machine learning and data science.

I hope my answer helps you. All the very best for your future endeavors!
