  • ArcGIS python field 字段

    The field object represents a column in a table. A field has many properties, the most obvious ones being its name and its type. 
    
    讨论
    Field properties can be accessed through the ListFields and Describe functions. 
    
    Updating a field property only updates the field object, no changes are made to the actual field in the table or feature class.
