How can I use the Console part of IDLE or Xcode playground just as it is seen on Python Flask basics video.

I've been using workplace for quite a while and it's great and everything but I am confused about the use of the "Console" part. Sometimes the person explaining let's say python and the use of Flask he goes to the Console part and he actually types in on it. I want to be able to do that outside workplace. let's say I want to use some code on my Xcode app or Idle for Python and try to type in whatever info the person teaching is on treehouse without using the workplace function you provide. How do I do that? or maybe it's like on Idle where the new file has only one part to write code and there is no console part below.I want to replicate what he does but I feel stuck on that part. I would appreciate it if you could explain me that guys.
