How to access command line


#1

I am currently learning python, working on this: https://www.codecademy.com/courses/learn-python-3/informationals/python3-customer-service-bot

The project tells me that I have to learn the command line. I finished it. Now I have to learn about Jupyter notebooks (https://www.codecademy.com/articles/how-to-use-jupyter-notebooks-py3)

The instructions say to open a terminal or whatever and type things in to check if I have python installed or whatever, but I never actually learned how to open a terminal in the command line course.

Are terminals only for apple? Can I not do this on windows?
If nott, how can I get the same thing so I can follow along? Any apps I need to install? I tried using command prompt and Anaconda prompt but those dont work.
