cf.VariableList

class cf.VariableList(sequence=())

Bases: cf.utils.CfList

An ordered sequence of variables stored in a list-like object.

In some contexts, whether an object is a variable or a variable list is not known and does not matter. So to avoid ungainly type testing, some aspects of the VariableList interface are shared by a variable and vice versa.

Any attribute or method belonging to a variable may be used on a variable list and will be applied independently to each element.

Just as it is straight forward to iterate over the variables in a variable list, a variable will behave like a single element variable list in iterative and indexing contexts.

Initialization

Parameters :

sequence : iterable, optional

Define a new list with these elements.

VariableList attributes

subspace

Subspace each variable in the list, returning a new list of variables.
