Is there a command like Mathematica's Dynamic in Sage?
I'm on a Mac with OS 10.11.6 and I'm using Sage 7.2's notebook interface. I did things in Mathematica that I want to check in Sage, but I'm a beginner at Sage. In Mathematica it's possible to keep track of the execution of my code, especially to detect when it's hanging, by using the Mathematica Dynamic command. Is there anything like this command in Sage, or is there perhaps another way to track the progress of the execution of a lengthy computation that will let me know in real time if and when it hangs? At the moment I insert print commands in my code that result in thousands of tuples of values of a tuple of variables streaming vertically down my screen. Messy. I'd rather see the values of such a tuple simply update in place as they do, say, on a digital clock. (This is what Dynamic achieves in Mathematica.)
