#查询条件，例如[系统级别]='一级'

#输出数据的后缀，例如将所有一级的输出内容加"_1"，则DLGX.shp输出后即为DLGX_1.shp
suffix = arcpy.GetParameterAsText(2)
#输出文件夹
output_folder = arcpy.GetParameterAsText(3)
#用于过滤的字段名
fieldname=arcpy.GetParameterAsText(4)
#无该字段时是否输出全部内容
isAllExp=arcpy.GetParameterAsText(5)

#unique shapefile names as keys, and with their file path as values.

        output = os.path.join(output_folder,fc[:-4]+suffix+".shp")
