写一个Python2.7的arcgis工具箱脚本：用来删除数据的所有字段

以下是一个Python 2.7的ArcGIS工具箱脚本，用于删除数据的所有字段：

import arcpy

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

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

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

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

        return [fc_param]

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

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

        # Loop through the list of fields and delete each one
        for field in fields:
            arcpy.DeleteField_management(fc, field.name)

        arcpy.AddMessage("All fields have been deleted from " + fc)

使用此脚本时，只需将其添加到ArcGIS工具箱中，然后将其作为工具在ArcMap或ArcCatalog中使用即可。该工具将要求用户提供要删除所有字段的要素类或表的路径。一旦脚本运行完毕，所有字段都将从该要素类或表中删除。
