关于arcpy中Table，FeatureClass处理中常用工具整理
1、遍历工具：
ListFeatureClasses ({wild_card}, {feature_type}, {feature_dataset})
ListTables ({wild_card}, {table_type})

2、操作Row，包括insert、delete、update。
首先，用游标Cursor，逐行扫描Row，找到需要修改的行（Cursor详细内容:http://help.arcgis.com/zh-cn/arcgisdesktop/10.0/help/index.html#/na/000v00000068000000/），在遍历FeatureClass，所用到的遍历方式有
InsertCursor，SearchCursor，UpdateCursor三种，具体信息（http://help.arcgis.com/zh-cn/arcgisdesktop/10.0/help/index.html#/na/000v00000068000000/）。
通过三种不同的Cursor，执行对应的操作，常用才Cursor操作见下表：
| 方法 | 说明 |
| deleteRow (row) |
Deletes a row in the database. The row corresponding to the current position of the cursor will be deleted. |
| insertRow (row) |
Inserts a new row into the database. |
| newRow () |
Creates an empty row object. |
| next () |
Returns the next object at the current index. |
| reset () |
Sets the current enumeration index (used by the next method) back to the first element. |
| updateRow (row) |
The updateRow method can be used to update the row at the current position of an update cursor. |

| 方法 | 说明 |
| getValue (field_name) |
Gets the field value. |
| isNull (field_name) |
Is the field value null. |
| setNull (field_name) |
Sets the field value to null. |
| setValue (field_name, object) |
Sets the field value. |
