spacepy.datamodel.dmarray

class spacepy.datamodel.dmarray(input_array, attrs=None, dtype=None)[source]

Container for data within a SpaceData object

Raises
NameError

raised is the request name was not added to the allowed attributes list

Examples

>>> import spacepy.datamodel as datamodel
>>> position = datamodel.dmarray([1,2,3], attrs={'coord_system':'GSM'})
>>> position
dmarray([1, 2, 3])
>>> position.attrs
{'coord_system': 'GSM'}a

The dmarray, like a numpy ndarray, is versatile and can store any datatype; dmarrays are not just for arrays.

>>> name = datamodel.dmarray('TestName')
dmarray('TestName')

To extract the string (or scalar quantity), use the tolist method

>>> name.tolist()
'TestName'

addAttribute(name[, value])

Method to add an attribute to a dmarray equivalent to a = datamodel.dmarray([1,2,3]) a.Allowed_Attributes = a.Allowed_Attributes + ['blabla']

addAttribute(name, value=None)[source]

Method to add an attribute to a dmarray equivalent to a = datamodel.dmarray([1,2,3]) a.Allowed_Attributes = a.Allowed_Attributes + [‘blabla’]
