Why there is different versions of Python on Atom IDE console and in terminal?

I'm new to Python and in web dev and now I'am learning to code with Django. I'm using Atom IDE and I installed Anaconda with Python version 3.8.2.

But when I activate VirtualEnvironment and type Atom console "python" and see that the installed version of python is 2.7.16.

When I use terminal and do the same thing I see that python version is 3.8.2 as expected.

If I type in Atom "Python3" I see 3.7.3 version for some reason.

Why in Atom I see such old version of Python? And why if I type python3 I see version lower than I installed and why in the terminal I see what I expect but not i Atom?

Thank you!
