feature_classes = arcpy.listFeatureClasses() # 打印要素类列表 forfcinfeature_classes: print(fc) 这个函数返回一个列表,其中包含了工作空间中所有的要素类名称。然后,你可以使用这个列表来执行其他与要素类相关的操作,如读取、修改、删除等。 需要注意的是,这个函数只返回工作空间中的要素类。如果你想获取其他类...

I know there are several ways to do this, but I decided to to use ListFeatureClasses function. I got the following sample code from ArcGIS website, but I do not know what changes I need to make in order for it to work. I barely started studying Python, so I know very basic stuff...

By default, notes overlays or client-side graphics from the web app are stored in an in-memory workspace. The in-memory workspace is temporary and is deleted when the app is closed. To make a permanent copy of the output project that contains notes overlays, specify anotes_gdband use the...
