Hi, if I have this code with a TVectorD:
import ROOT
tv = ROOT.TVectorD(3)
for i in range(3):
tv[i] = i
L = list(tv)then L contains a python list of the contents of the TVectorD. If I try the same thing with a TArrayD, I get an infinite-scrolling error message about out-of-bounds access. Try it yourself:
import ROOT
ta = ROOT.TArrayD(3)
for i in range(3):
ta[i] = i
L = list(ta)I have to kill the terminal to end the error messages, so I couldn’t easily copy & paste the error message.
Interestingly, if I create a 0-length default-constructed TVectorD/TArrayD, I still get errors with the TArrayD, but they are more readable and Ctrl+C-able (this is in IPython:)
In [4]: ta = ROOT.TArrayD()
In [5]: list(ta)
Error in <TArrayD::operator[]>: index 0 out of bounds (size: 0, this: 0x7fb366a1e6c0)
