 """Return a Collection aligned with this one composed of one repeated value. Aligned Data Collections are of the same Data Collection class, have the same number of values and have matching datetimes. Args: value: A value to be repeated in the aliged collection values or A list of values that has the same length as this collection. Default: 0. data_type: The data type of the aligned collection. Default is to use the data type of this collection. unit: The unit of the aligned collection. Default is to use the unit of this collection or the base unit of the input data_type (if it exists). mutable: An optional Boolean to set whether the returned aligned collection is mutable (True) or immutable (False). The default is None, which will simply set the aligned collection to have the same mutability as the starting collection. """
