List fields of 'Float' type in a feature class using arcpy.ListFields()

MattHowe — Wed, 21 Sep 2022 08:11:59 GMT

I have a shapefile containing fields of float type of which I have exported to a file geodatabase. I would like to list only the fields of float type in the resultant feature class but float isn't an option and gives an empty list.

[f.name for f in arcpy.ListFields("Test") if f.type == 'Float'] []

Double is fine of course.

[f.name for f in arcpy.ListFields("Test") if f.type == 'Double'] ['H10_iso', 'H12_iso', 'H15_iso', 'H16_iso', 'H17_iso', 'H18_iso', 'H20_iso']

Would I need to create fields of double type in the feature class and update the values or is there another way?

Float fields are listed as Single:

table = arcpy.management.CreateTable("memory", "bla") arcpy.management.AddField(table, "FloatField", "FLOAT") arcpy.management.AddField(table, "DoubleField", "DOUBLE") for f in arcpy.ListFields(table): print(f.name, f.type) #OBJECTID OID #FloatField Single #DoubleField Double

You could also specify the type you want directly in ListFields using field_type.
