Codebeispiel
Display FieldInfo properties for a feature layer.
import arcpy
fc = "C:/Data/wells.shp"
layer = "temp_layer"
arcpy.MakeFeatureLayer_management(fc, layer)
# Create a describe object
#
desc = arcpy.Describe(layer)
# If a feature layer, continue
#
if desc.dataType == "FeatureLayer":
# Create a fieldinfo object
#
fieldInfo = desc.fieldInfo
index = 0
# Use the count property to iterate through all the fields
#
while index < fieldInfo.count:
# Print fieldinfo properties to the screen
#
print "Field Name: " + fieldInfo.getFieldName(index)
print "\tNew Name: " + fieldInfo.getNewName(index)
print "\tSplit Rule: " + fieldInfo.getSplitRule(index)
print "\tVisible: " + fieldInfo.getVisible(index)
index += 1
