cf.Data.full

classmethod Data.full(shape, fill_value, dtype=None, units=None, calendar=None, chunks='auto')[source]

Return a new array of given shape and type, filled with a fill value.

See also

empty, ones, zeros

Parameters
shape: int or tuple of int

The shape of the new array. e.g. (2, 3) or 2.

fill_value: scalar

The fill value.

dtype: data-type

The desired data-type for the array. The default, None, means np.array(fill_value).dtype.

units: str or Units

The units for the new data array.

calendar: str, optional

The calendar for reference time units.

chunks: int, tuple, dict or str, optional

Specify the chunking of the underlying dask array.

Any value accepted by the chunks parameter of the dask.array.from_array function is allowed.

By default, "auto" is used to specify the array chunking, which uses a chunk size in bytes defined by the cf.chunksize function, preferring square-like chunk shapes.

Parameter example:

A blocksize like 1000.

Parameter example:

A blockshape like (1000, 1000).

Parameter example:

Explicit sizes of all blocks along all dimensions like ((1000, 1000, 500), (400, 400)).

Parameter example:

A size in bytes, like "100MiB" which will choose a uniform block-like shape, preferring square-like chunk shapes.

Parameter example:

A blocksize of -1 or None in a tuple or dictionary indicates the size of the corresponding dimension.

Parameter example:

Blocksizes of some or all dimensions mapped to dimension positions, like {1: 200}, or {0: -1, 1: (400, 400)}.

New in version 3.14.0.

Returns
Data

Array of fill_value with the given shape and data type.

Examples

>>> d = cf.Data.full((2, 3), -99)
>>> print(d.array)
[[-99 -99 -99]
 [-99 -99 -99]]

>>> d = cf.Data.full(2, 0.0)
>>> print(d.array)
[0. 0.]

>>> d = cf.Data.full((2,), 0, dtype=bool)
>>> print(d.array)
[False False]
