C array to python array

ROOT
3

Hello wim,

Thanks for your answer.

Indeed, passing a numpy.array to a C function such as TH1D::FillN(int, double* double*) works. I’m actually using this in my scripts.

But I could not reverse the procedure. The numpy.array constructor doesn’t take size as argument : doing something like

c_pointer_object = giveArray(10)
a = numpy.array(c_pointer_object)

crashes python (the contrary would have surprised me). I was wandering if there are known workaround …

P.A.
