cf.FieldList.select_by_property

FieldList.select_by_property(*mode, **properties)

Select field constructs by property.

To find the inverse of the selection, use a list comprehension with match_by_property method of the field constucts. For example, to select all field constructs which do not have a long_name property of ‘Air Pressure’:

>>> gl = cf.FieldList(f for f in fl if not
...                   f.match_by_property(long_name='Air Pressure))

New in version 3.0.0.

Parameters

mode: optional

Define the behaviour when multiple properties are provided.

By default (or if the mode parameter is 'and') a field construct is selected if it matches all of the given properties, but if the mode parameter is 'or' then a field construct will be selected when at least one of its properties matches.

properties: optional

Select field constructs. May be one or more of:

• The property of a field construct.

By default a field construct is selected if it matches all of the given properties, but it may alternatively be selected when at least one of its properties matches (see the mode positional parameter).

A property value is given by a keyword parameter of the property name. The value may be a scalar or vector (e.g. 'air_temperature', 4, ['foo', 'bar']); or a compiled regular expression (e.g. re.compile('^ocean')), for which all constructs whose methods match (via re.search) are selected.

Returns

FieldList

The matching field constructs.
