Programmatically list all variables of a NetCDF file using netCDF4 and Python

Question

How do I programmatically list all variables of a NetCDF file that I have read in using netCDF4 and Python?

import netCDF4
dset = netCDF4.Dataset('test.nc')

Answer 1

From the documentation, here, it looks like it would just be:

import netCDF4
dset = netCDF4.Dataset('test.nc')
dset.variables
