The Importance of a Python Tutor

Python tutor is a tool that shows how different languages differ from each other. In Ruby, for example, you can't access what looks like a global variable in the scope of your normal thing. So if you actually think of things in a Python way and you're doing Ruby, it gets super confusing in terms of scope. And I want this tool to be useful not only for someone who's an absolute beginner who's never learned anything, but also for experienced programmers.
