Hi All,

I am trying to translate some CINT based macro into a pyROOT one. Can anybody help me with following snippet:

//===================================================

int event;
float char_array[n];
Zee=new TTree("Zee","Zee");
Zee->Branch("event", &event, "event/I"); Zee->Branch("char_array", char_array, "char_array[n]/F");

//================================================

I hope that &event can be replaced by AddressOf(nevent), but how should i deal with arrays?? Should they now be defined as "lists" or "tuples", how should one assign them to specific tree branches ?

cheers
