1.3.5. FAQ: a Python handbook to interact with Uranie

This section introduces some frequently asked methods to help handling data and objects (as many objects proposed are either ROOT or C++-based). Some of these methods are used throughout the examples in the macros in Use-cases in Python, but the aim here is to gather everything that might be of use for a python user that would like to put his hand on Uranie. Most of this methods rely on ROOT version being greater than 6.20 but the modification are small if one uses older versions (as long as it is greater than6).
