 Parameters
 value: optional
The period. The absolute value is used. May be set to any numeric scalar object, including
numpy
andData
objects. The units of the radius are assumed to be the same as the data, unless specified by aData
object.If value is
None
then any existing period is removed from the construct.
 Returns
Examples:
>>> print(c.period()) None >>> c.Units <Units: degrees_east> >>> print(c.period(360)) None >>> c.period() <CF Data(): 360.0 'degrees_east'> >>> import math >>> c.period(cf.Data(2*math.pi, 'radians')) <CF Data(): 360.0 degrees_east> >>> c.period() <CF Data(): 6.28318530718 radians> >>> c.period(None) <CF Data:() 6.28318530718 radians> >>> print(c.period()) None >>> print(c.period(360)) None >>> c.period() <CF Data(): 360.0 degrees_east>
