is it important to learn c++ if python is known?

Answer 1

Importance relies quite a lot on your goals and the realities of them. What I think is important may mean nothing to you.

What may be more important is to contrast the languages and their purposes (which came from their objectives...or goals). For example in terms of safety: C++ assumes 'you meant to do that' and lets you. It has no safety. Python is more cautious and has a lot. Java is somewhere in between.

Some people are better with safeties, some get more done without them. And there are other pros/cons too. Programmers try to make computers do 'work' for them/others. What works for you?

Note you can extend Python with C++: https://docs.python.org/2/extending/extending.html

Answer 2

Compiled languages make faster programs. So I would recommend to learn at least one, yeah.

Answer 3

If you want to be a programmer or software engineer, my answer is yes. C++ is a very known language and has a lot of opportunities. By the way it isnt difficult to learn an other programming language after you know thr basics od programming :)
