ListFeatureClasses

摘要

可返回当前工作空间中受名称、要素类型和可选要素数据集限制的要素类的列表。

说明

必须先设置工作空间环境，然后才能使用多个列表函数，包括 ListDatasets、ListFeatureClasses、ListFiles、ListRasters、ListTables 和 ListWorkspaces。

语法

ListFeatureClasses ({wild_card}, {feature_type}, {feature_dataset})

参数	说明	数据类型
wild_card	限制返回的结果。如果未指定某一值，则返回所有值。通配符不区分大小写。 符号 说明 示例 * 表示零个或多个字符。 Te* 可找到田纳西州和德克萨斯州。	String
feature_type	The feature type that will limit the results. Valid feature types are listed in the following table: Annotation—Annotation feature classes Arc—Arc (or polyline) feature classes Dimension—Dimension feature classes Edge—Edge feature classes Junction—Junction feature classes Label— Label feature classes Line—Polyline (or arc) feature classes Multipatch—Multipatch feature classes Multipoint—Multipoint feature class Node—Node feature classes Point—Point feature classes Polygon—Polygon feature classes Polyline—Polyline (or arc) feature classes Region—Region feature classes Route—Route feature classes Tic—Tic feature classes All— All feature classes in the workspace. This is the default. (默认值为 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

返回值

数据类型	说明
String	该函数返回包含要素类名称的列表，该列表受可选的 wild_card、feature_type 和 feature_dataset 参数的限制。

代码示例

ListFeatureClasses 示例

将 shapefile 复制到地理数据库中。

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.management.CopyFeatures(
        fc, os.path.join("c:/base/output.gdb",
                         os.path.splitext(fc)[0]))

ListFeatureClasses 示例 1

列出地理数据库中所有的要素类，包括要素数据集中的所有要素类。

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)
