Agreed! Those quantum mechanics people do love Fortran. I talked a bit with Schrödinger (the company) around 1997 about a job in molecular visualization, and decided I didn't want to be the lone non-Fortran developer in a company. I&#x

I've worked in small molecule drug discovery for about 25 years and have only used one Fortran program directly, DGEOM95. And that was in the late 1990s. Otherwise, it's mostly C, C++, and Python, with a smattering of other langua

That's not really the issue with argparse and subcommands. argparse with subcommands generally requires specifying all of the options for all of the subcommands, even if you only want one subcommand. These in turn may require importing
