ArcPy学习入门（二）：创建Python脚本

1、创建新 Python 脚本

# coding=utf- 8
"" "-----------------------------------------------------------------------------
  Script Name: Clip Multiple Feature Classes
  Description: Clips one or more shapefiles
               from a folder and places the clipped
               feature classes into a geodatabase.
  Created By:  Insert name here.
  Date :        Insert date here.
----------------------------------------------------------------------------- "" "

# Import ArcPy site- package  and os modules
import  arcpy
import  os

# Set the input workspace
arcpy.env.workspace = arcpy.GetParameterAsText( 0 )

# Set the clip featureclass
clipFeatures = arcpy.GetParameterAsText( 1 )

# Set the output workspace
outWorkspace = arcpy.GetParameterAsText( 2 )

# Set the XY tolerance
clusterTolerance = arcpy.GetParameterAsText( 3 )

try :
    # Get a list of the featureclasses  in  the input folder
    fcs = arcpy.ListFeatureClasses()

    for  fc  in  fcs:
        # Validate the  new  feature  class  name  for  the output workspace.
        featureClassName = arcpy.ValidateTableName(fc, outWorkspace)
        outFeatureClass = os.path.join(outWorkspace, featureClassName)

        # Clip  each  feature  class  in  the list  with  the clip feature  class .
        # Do not clip the clipFeatures, it may be  in  the same workspace.
        if  fc != os.path.basename(clipFeatures):
            arcpy.Clip_analysis(fc, clipFeatures, outFeatureClass,
                                clusterTolerance)

except Exception  as  err:
    arcpy.AddError(err)
    print err

该脚本将采用以下四个参数，以便实现通用：

• 用来定义待处理的那组要素类的输入工作空间

• 通过裁剪工具对输入要素类进行裁剪的区域的要素类

• 写入裁剪工具结果的输出工作空间

• 裁剪工具使用的 XY 容差

         ValidateTableName() 函数用于确保输出名称对输出空间有效；os.path.basename()方法用于获取处理裁剪要素类的名称（不包含路径）。
