5. Belle II Python Interface

The Belle II Software has an extensive interface to the Python 3 scripting language: All configuration and steering is done via python and in principle also simple algorithms can be implemented directly in python. All main functions are implemented in a module called basf2 and most people will just start their steering file or script with

import basf2
main = basf2.Path()
