How do I plot the python output data in 3D with realtime update?

How do I plot the python output data in 3D with realtime update?

I'm new to python and I coded a program with tons of 5 sets of 3
coordinates (5*3 lists). I wanted to track the position of the five points
and hope it can update instantly while the program is running (if not
that's fine). Since there are so many data (over 100000 sets), it is
inconvenient to output and plot by matlab. I downloaded VPython module but
I cannot plot in 3d. I found VPython really convenient but my program
involves complicated calculations so that loops can reduce many lines.
Sorry for a long question, but in short, I wanted a module or something
can visualize output of my data in 3d and update from time to time.
Thanks. Python version: 2.7
