Question

我在arcgis中运行这段代码，总是提示line14有错误,修改多次未成功，想让你们帮看看问题出在哪

# 1. 导入 arcpy 和 os 模块
import arcpy
import os

# 2. 定义函数 check_shp_fields，参数为 workspace
def check_shp_fields(workspace):
    # 3. 设置 arcpy 的工作空间
    arcpy.env.workspace = workspace

    # 4. 获取 SHP 文件列表
    shp_files = arcpy.ListFeatureClasses()

    # 5. 检查 SHP 文件的字段
    for shp_file in shp_files:
        # 6. 获取 SHP 文件路径
        shp_path = os.path.join(workspace, shp_file)

        # 7. 获取 SHP 文件的字段信息
        fields = arcpy.ListFields(shp_path)

        # 8. 检查字段是否为空值或必填字段为空
        for field in fields:
            field_name = field.name
            is_required = field.required

            # 9. 使用 SearchCursor 遍历字段值
            with arcpy.da.SearchCursor(shp_path, [field_name]) as cursor:
                for row in cursor:
                    value = row[0]

                    # 10. 检查字段是否为空值
                    if value is None or value == "":
                        arcpy.AddWarning("Unqualified SHP file: {}\nField: {}\nReason: Field value is empty.".format(shp_file, field_name))
                        break

                    # 11. 检查字段是否为必填字段但值为空
                    if is_required and (value is None or value == ""):
                        arcpy.AddWarning("Unqualified SHP file: {}\nField: {}\nReason: Required field value is empty.".format(shp_file, field_name))
                        break

# 12. 从参数中获取工作空间
workspace = arcpy.GetParameterAsText(0)

# 13. 调用函数进行 SHP 文件字段检查
check_shp_fields(workspace)

报错信息是什么，贴出来看
多半是shp_files这个东西是个None
