Zusammenfassung
From the parameter list, select the desired parameter by its index or its name. The parameter is returned as an object.
Hinweis:
The GetParameter function is for use with script tools (.tbx, .atbx). For a Python toolbox (.pyt) tool, access a parameter's value using the Parameter object's value property.
Diskussion
To use the parameter as a text string instead, see the GetParameterAsText function.

arcpy.AddMessage("Name is: {0}".format(spatial_ref.name))
arcpy.AddMessage("Type is: {0}".format(spatial_ref.type))
arcpy.AddMessage("Factory code is: {0}".format(spatial_ref.factoryCode))Get a script tool parameter as an object. The script tool has one parameter named in_spatial_reference, that accepts a spatial reference object. The parameter is selected by its name.
