[Matplotlib-users] matplotlib interactive in a shell terminal?

[Raphael Raccuia]

Hi,
thank you for your answers!

I saw about ipython, I would have used that but I use the [shell] object 
in Puredata (music object programmation language) which just send 
commands to terminal, that's why...
There is a Python object, but only works with 2.7.
