There are the trees which labeled with whitespace in my root file. How can i refer to that trees in python programm?
I used the following construction:
myFile.Get("tree name") should do the job. You can find the TFile documentation in our reference guide – all C++ methods can be called from Python as well.
Thanks a lot.
That trees cosist from values of axis X and axis Y. But program performed only information about size of branches, but not necessary information.
TTree::Print outputs some general information about the TTree schema (which branches/columns are present, their type, size etc.). If you want to print the TTree contents you can use e.g. Scan instead.
