nctoolkit.DataSet.divide

DataSet.divide(x=None, var=None)

divide: Divide the data.

This will divide the dataset by a constant, another dataset or a netCDF file.

Parameters:

  • x (int, float, DataSet or netCDF file) – An int, float, single file dataset or netCDF file to divide the dataset by. If a dataset or netCDF file is supplied, this must have only one variable, unless var is provided. The grids must be the same.

  • var (str) – A variable in the x to use for the operation

Examples

If you wanted to divide all variables in a dataset by 20, you would do the following:

>>> ds.divide(10)

Or, you could use standard python division syntax:

>>> ds / 10

To divide values in a dataset by those in the dataset ds2 from a dataset ds1, you would do the following:

>>> ds1.divide(ds2)

Or, you could use standard python division syntax:

>>> ds1 / ds2

Grids in the datasets must match. Division will occur in matching timesteps in ds1 and ds2. If there is only 1 timestep in ds2, then the data from that timestep in ds2 will divided the data in all ds1 time steps.
