GetParameter

サマリー

From the parameter list, select the desired parameter by its index or its name. The parameter is returned as an object.

注意:

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.

説明

To use the parameter as a text string instead, see the GetParameterAsText function.

import arcpy

# Get the spatial reference from the tool dialog.
spatial_ref = arcpy.GetParameter(0)

# Display the Spatial Reference properties
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))

GetParameter example 2

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.

import arcpy

# Get the spatial reference from the tool dialog.
spatial_ref = arcpy.GetParameter("in_spatial_reference")

# Display the Spatial Reference properties
arcpy.AddMessage(f"Name is: {spatial_ref.name}")
arcpy.AddMessage(f"Type is: {spatial_ref.type}")
arcpy.AddMessage(f"Factory code is: {spatial_ref.factoryCode}")
