If you are using an up-to-date netcdf4-python module and w was returned from a
createDataset
or createGroup call, then that should work, as this example from the docs shows:
>>> fcstgrp1 = rootgrp.createGroup("/forecasts/model1")
>>> fcstgrp2 = rootgrp.createGroup("/forecasts/model2")
See the docs at http://unidata.github.io/netcdf4-python/ for more info on using
createGroup for
creating nested subgroups. If it doesn't work, it's a bug that should be
reported on the GitHub
site by creating an "issue" here:
