oocgcm.core.grids.generic_2d_grid.__getitem__

generic_2d_grid.__getitem__(item)

The behavior of this function depends on the type of item.

• if item is a string, return the array self._arrays[item]
• if item is a slice, a grid object restricted to a subdomain.

Use slicing with caution, this functionnality depends on the order of the dimensions in the netcdf files.

Parameters:

item : slice or str

item can be a string identifying a key in self._arrays item can be a slice for restricting the grid to a subdomain.

Returns:

out : xarray.DataArray or generic_2d_grid

either a dataarray corresponding to self._arrays[item] or a new grid object corresponding to the restructed region.
