cf.AncillaryVariables

class cf.AncillaryVariables(fields=None)

Bases: cf.fieldlist.FieldList

A sequence of ancillary variable fields stored in a list-like object.

Initialization

Parameters :

fields : (sequence of) cf.Field, optional

Create a new field list with these fields.

Examples

>>> fl = cf.FieldList()
>>> len(fl)
0
>>> f
<CF Field: air_temperature() K>
>>> fl = cf.FieldList(f)
>>> len(fl
1
>>> fl = cf.FieldList([f, f])
>>> len(fl)
2
>>> fl = cf.FieldList(cf.FieldList([f] * 3))
>>> len(fl)
3

AncillaryVariables attributes

subspace
