How do I loop over all bins of a TH2 from .root file using pyROOT?
Eventually I want to try and distinguish the color of the bin after I loop over it.
P.S. This is what I have so far:
import ROOT
//create a 2D histogram
histo2 = ROOT.TH2F(“histo2”,"",200,-5,5,200,-5,5)
//loop over the bins of TH2
for i in range(1,histo2.GetNbinsX() + 1):
for j in range(1,histo2.GetNbinsY() + 1):
