In a Python toolbox, the parameter's datatype property is set using the Parameter class in the getParameterInfo method.
def getParameterInfo(self): #Define parameter definitions # First parameter param0 = arcpy.Parameter( displayName="Input workspace", name="in_workspace", datatype="DEWorkspace", parameterType="Required", direction="Input")
Composite data types
Occasionally, the need arises for a parameter to accept multiple data types, often referred to as a composite data type. In a Python toolbox, composite data types are defined by assigning a list of data types to the parameter's datatype property. In the example below, a parameter is defined that accepts a Raster dataset or a Raster catalog.
def getParameterInfo(self): #Define parameter definitions # First parameter param0 = arcpy.Parameter( displayName="Input Raster Dataset", name="in_rasterdataset", datatype=["DERasterDataset", "DERasterCatalog"], parameterType="Required", direction="Input")
