写一个arcgis工具箱脚本自动删除图层的所有字段

下面是一个arcgis工具箱脚本，可以自动删除指定图层的所有字段：

import arcpy

class Toolbox(object):
    def __init__(self):
        self.label = "Delete Fields"
        self.alias = "Delete Fields"

        # List of tool classes associated with this toolbox
        self.tools = [DeleteFields]

class DeleteFields(object):
    def __init__(self):
        self.label = "Delete Fields"
        self.description = "Deletes all fields in a specified feature class or table."
        self.canRunInBackground = False

    def getParameterInfo(self):
        fc_param = arcpy.Parameter(
            displayName="Input Feature Class or Table",
            name="fc",
            datatype="DEFeatureClass",
            parameterType="Required",
            direction="Input")

        return [fc_param]

    def execute(self, parameters, messages):
        fc = parameters[0].valueAsText

        # Get list of fields in feature class or table
        fields = arcpy.ListFields(fc)

        # Loop through fields and delete them
        for field in fields:
            arcpy.DeleteField_management(fc, field.name)

        messages.addMessage("All fields have been deleted from " + fc)

将以上代码保存为一个.py文件，然后通过ArcGIS工具箱将其添加为工具。运行该工具时，输入要删除字段的图层即可。
