class astropy.io.misc.ecsv.ColumnECSV(name, datatype, subtype=None, unit=None, description=None, format=None, meta=None)[source]#

Bases: object

Class representing attributes of a column in an ECSV header.

Parameters:

namepython:str: The name of the column.
datatypepython:str: The data type of the column as specified in the ECSV header.
subtypepython:str or python:None, optional: The subtype of the column, if applicable.
unitpython:str or python:None, optional: The unit of the column values, if specified.
descriptionpython:str or python:None, optional: A description of the column.
formatpython:str or python:None, optional: The format string for the column values.
metapython:dict or python:None, optional: Additional metadata associated with the column.

Attributes:

csv_np_typepython:str: Numpy type string describing the column CSV data. In practice this is the same as the ECSV datatype except that “string” => “str”. This is provided to the engine convert_np_type() method to generate the engine-specific type provided to the CSV reader. For instance, for pandas the int32 type gets converted to Int32 to read columns as a nullable int32.
dtypenumpy.dtype: Numpy dtype in the final column data. This may be entirely different from csv_np_type in some cases, in particular JSON-encoded fields.
shapepython:tuple of python:int: Shape of the final column data.
