zcollection.partitioning.date.Date

class zcollection.partitioning.date.Date(variables, resolution)

Bases: Partitioning

Initialize a partitioning scheme based on dates.

Parameters:

• variables (Sequence[str]) – A list of strings representing the variables to be used for partitioning.

• resolution (str) – Time resolution of the partitioning. Must be in RESOLUTION.

Raises:

ValueError – If the resolution is not in the list of supported resolutions or if the partitioning is not performed on a one dimensional variable.

Example

>>> partitioning = Date(variables=("time", ), resolution="Y")

Attributes

resolution	The time resolution of the partitioning
ID	The ID of the partitioning scheme
variables	Variables to be used for the partitioning.
