calculating multiple polylogarithms in sage/pynac
In connection with some numerical simulations I am running, I need to calculate multiple polylogarithms to high precision ( 20 digits or more). I know that there exists functions in the Ginac library that can handle this, but I would rather work in python, hence I was wondering whether similar functionality exist here. If so how do I acces it (have been looking around in the documentation, but haven't found any mention of multiple polylogs). Any help would be most welcome. Thanks!
