Well, generally recommend python.
It's really easy to learn because of its syntax, but being an interpreted language is slower compared to something like C++ which is compiled.
Also, if you are going to learn python, I'd recommend installing 'anaconda' so you can have easy access to the multitude of libraries of python for scientific and data science applications, plus the easy creation of environments.
As for the IDE, I personally use pycharm community edition, but any should be fine.
