Hi experts,
I am trying to loop a tree and simply getting a value on one of its branch.
The catch is the branch name has a dot in it, eg. HGamEventInfoAuxDyn.pT_yy. I dont think the python syntax likes this as it gives an segmentation error.
Below is a snippet of my code.
for i in range( tree.GetEntries() ):
tree.GetEntry(i)
yy_pt = tree.HGamEventInfoAuxDyn.pT_yy
print(yy_pt)
Any idea on how to get around this?
Thanks!
Best,
Yosse
Attach the output of: tree.Print()
Here are the first 50 branches outputted by the Print().

Before the “for” loop, try to add: tree.SetMakeClass(1)
You can try:
for entry in tree:
yy_pt = getattr(entry, "HGamEventInfoAuxDyn.pT_yy")
print(yy_pt)
This solution works! Thanks a lot!
