Oh, CERN? I think they have made PyROOT which is horrible? (And even a jupyter kernel for interactive use.) In terms of scripting, a professor once showed us a workflow script from his old days written entirely in bash and is very very long and very complex. He basically said if your script gets that complicated it should be written in Python nowadays. But Python’s HPC presence is deeper than scripting in that sense. Machine learning frameworks definitely is a contributing factor, but even more traditional HPC workflows are benefited when stuffs have Python API, especially with mpi4py. I once used something called mpi bash that I need to compile it myself on an HPC platform. It is much less well known and used, perhaps because of what the professor said—if it needs MPI, probably even for scripting it should be scripted in Python instead.
