Calling GetLowEdge in pyROOT

I am trying to call the TH1 method GetLowEdge in pyROOT, which has the signature

void TH1::GetLowEdge(Double_t* edge) const

How do I call this method in pyROOT? I don’t know how to recreate the Double_t* type in python. Anyone know?

You will find plenty of python examples here: … yroot.html
