cf.AncillaryVariables.getattr

AncillaryVariables.getattr(attr, *default)

Get a named attribute from each element of the list.

fl.getattr(attr, *default) is equivalent to cf.List(for f in fl: getattr(f, attr, *default)).

Parameters :

attr : str

The attribute’s name.

default : optional

When a default argument is given, it is returned when the attribute doesn’t exist; without it, an exception is raised in that case.

Returns :

out : cf.List

Each element’s attribute value.
