Summary
Provides information about attribute parameters associated with the network analysis layer.
Discussion
The attributeName, parameterName, and parameterValue properties for the attribute parameter object are dynamic. This means that the total number of properties supported by a given attribute parameter object depends on the parameterCount property. For example, if the value of the parameterCount property is 2, then the attribute parameter object will support attributeName0, attributeName1, parameterName0, parameterName1, parameterValue0, and parameterValue1 properties.
Properties
Property | Explanation | Data Type |
attributeNameX (Read Only) | The name of a network attribute for which the parameter is defined. | String |
parameterNameX (Read Only) | The name of the parameter. | String |
parameterValueX (Read Only) | The value for the parameter as specified in the network analysis layer. This parameter value is used during the solve operation. | Integer |

Network Analyst Layer Attribute Parameter example
Display the attribute parameter information for a network analysis layer.
# Name: NALayerAttributeParameterProperties_ex01.py
# Description: Prints the attribute parameter information for a given network
# analysis layernetwork analysis layer.
import arcpy
in_layer = "C:/Data/Route.lyr"
# Create Describe object from layer file.
desc = arcpy.Describe(in_layer)
count = desc.parameterCount
parameters = desc.parameters
# Print attribute parameter values
print "Total Attribute Parameters: ", count
for i in range(0, count):
attrName = getattr(parameters,"attributeName" + str(i))
paramName = getattr(parameters,"parameterName" + str(i))
paramValue = getattr(parameters,"parameterValue" + str(i))
print "%s : %s : %s" % (attrName,paramName,paramValue)
