Synthèse
Returns a list of the feature classes in the current workspace, limited by name, feature type, and optional feature dataset.
Discussion
The workspace environment must be set before using several of the list functions, including ListDatasets, ListFeatureClasses, ListFiles, ListRasters, ListTables, and ListWorkspaces.
Syntaxe
ListFeatureClasses ({wild_card}, {feature_type}, {feature_dataset})
Paramètre | Explication | Type de données | ||||||
wild_card | Limits the results returned. If a value is not specified, all values are returned. The wildcard is not case sensitive.
| String | ||||||
feature_type | The feature type that will limit the results. Valid feature types are listed in the following table:
(La valeur par défaut est All) | String | ||||||
feature_dataset | Limits the feature classes returned to the feature dataset, if specified. If blank, only stand-alone feature classes will be returned in the workspace. | String |
Type de données | Explication |
String | The list containing feature class names is returned from the function, limited by the optional wild_card, feature_type, and feature_dataset arguments. |
Exemple de code
Copy shapefiles to a geodatabase.
import os
import arcpy
# Set the workspace for ListFeatureClasses
arcpy.env.workspace = "c:/base"
# Use the ListFeatureClasses function to return a list of
# shapefiles.
featureclasses = arcpy.ListFeatureClasses()
# Copy shapefiles to a file geodatabase
for fc in featureclasses:
arcpy.CopyFeatures_management(
fc, os.path.join("c:/base/output.gdb",
os.path.splitext(fc)[0]))
List all feature classes in a geodatabase, including any in feature datasets.
import arcpy
import os
arcpy.env.workspace = "c:/base/gdb.gdb"
datasets = arcpy.ListDatasets(feature_type='feature')
datasets = [''] + datasets if datasets is not None else []
for ds in datasets:
for fc in arcpy.ListFeatureClasses(feature_dataset=ds):
path = os.path.join(arcpy.env.workspace, ds, fc)
print(path)
