Arcpy基础入门-6、遍历

1、列出所有的要素类

import arcpy

arcpy.env.workspace = "D:\用户目录\Documents\ArcGIS\可达性分析成果.gdb"

# Use Python's built-in function len to reveal the number of feature classes
#   in the workspace
fcs = arcpy.ListFeatureClasses()

fcCount = len(fcs)
for fc in fcs: 
    # Copy the features from the workspace to a folder
    #
    print fc
    

print fcCount

2、列出所有的数据集

import arcpy
arcpy.env.workspace = "D:\数据备份.gdb"

ds = arcpy.ListDatasets()

dsCount = len(ds)
for dataset in ds:
   print dataset
print dsCount

3、列出文件下所有的文件

import arcpy

arcpy.env.workspace = "E:\KuGou"

# Use Python's built-in function len to reveal the number of feature classes
#   in the workspace
files = arcpy.ListFiles()

fcCount = len(files)
for fc in files: 
    # Copy the features from the workspace to a folder
    #
    print fc
    

print fcCount

4、列出所有的栅格文件

import arcpy
import arcpy.sa

arcpy.env.workspace = "E:\LE71230392003097EDC00"

# Use Python's built-in function len to reveal the number of feature classes
#   in the workspace
rasterlist = arcpy.ListRasters()

fcCount = len(rasterlist)
for fc in rasterlist: 
    # Copy the features from the workspace to a folder
    #
    print fc
    

print fcCount
