The fields are returned from the Describe tool as a list of field objects A list of field objects can also be obtained using arcpy's ListFields method Use
How do I define a field in ArcGIS Pro?
To create a field, complete the following steps:
1Click the New Field button on the Fields tab or click the last row in the view that says Click here to add a new field. 2) Enter a name for the new field. 3) Double-click the Alias column and enter an alias for the field.
What is the describe tool in ArcGIS?
The Describe function returns a dictionary with multiple properties, such as data type, fields, indexes, and many others. The dictionary's keys are dynamic, meaning that depending on what data type is described, different properties will be available for use.
In ArcGIS Pro, available data types that can be applied to a field include a variety of numerical types (integers, float, double), text, date only, timestamp offset, binary large objects (BLOB), and globally unique identifiers (GUIDs).
How do you show fields in ArcGIS?
To turn all fields on or off, use the check box in the column header. Set the display formatting for numeric and date field types. Click the Determine display formatting for numeric and date field types button to open the Number Format dialog box.
