GetParameterAsText - List of Value

Question

Hi,

I want to define a list of values for a Parameter as all the values for a particular field in a Feature Class.

How do I do that?

You should be able to use Tool Validation for this. Also, see here for a working example, employing an arcpy.da.SearchCursor.

Hi Mitt,

I doubt you can define a parameter as values in a field. You can pass a shapefile and field as input parameter.

Refer this blog Create a list of unique field values | ArcPy Café  , get a list of values in your script and loop through the values.
