写一个arcgis工具箱脚本：用来删除要素图层的所有字段

下面是一个用 Python 编写的 ArcGIS 工具箱脚本，它可以删除要素图层的所有字段：

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 feature layer."
        self.canRunInBackground = False

    def getParameterInfo(self):
        params = []

        # Input feature layer parameter
        input_layer = arcpy.Parameter(
            displayName="Input Layer",
            name="input_layer",
            datatype="GPFeatureLayer",
            parameterType="Required",
            direction="Input")

        params.append(input_layer)

        return params

    def execute(self, parameters, messages):
        # Get input layer
        input_layer = parameters[0].valueAsText

        # Get list of fields in input layer
        field_list = [f.name for f in arcpy.ListFields(input_layer)]

        # Delete each field in list
        for field in field_list:
            arcpy.DeleteField_management(input_layer, field)

        messages.addMessage("All fields deleted from {}.".format(input_layer))

此脚本包含一个名为 "DeleteFields" 的工具类，它有一个名为 "execute" 的方法，该方法获取一个要素图层作为输入，并删除该图层的所有字段。要使用此工具，可以将其添加到 ArcGIS 工具箱中，并将要素图层作为输入传递给它。
