cf.Field.example_field

classmethod Field.example_field(n)

Return an example field construct.

New in version 3.0.4.

Parameters:

n: int

Select the example field construct to return, one of:

n	Description
1	The field construct has properties as well as a cell method constucts and dimension coordinate constructs with bounds.
2	The field construct has properties as well as at least one of every type of metadata construct.

See the examples for details.

Returns:

Field

The example field construct.
