Script to loop through Multiple Datasets

SteveKim1

Hi Everyone,

Is there a script where I can run through multiple datasets in a gdb. 

For example: I want to add fields to every feature class  which is grouped in their respective datasets. 

Thanks!

Oops, it looks like I should have read the documentation more closely.

What happened was that ListFeatureClasses just grabs everything from the workspace, ignoring the stuff in datasets, unless you specify that you want the stuff in the datasets.

You may also want to try out Walk(), like Joshua suggested.

arcpy.env.workspace =  r'=...\Data_Transfers.gdb'

field1 = "LATITURE" #These are mispelled
field2 ="LONGITURE"#These are mispelled

FDlist = arcpy.ListDatasets(feature_type='feature') #The parameter in here isn't strictly necessary
print(FDlist)
'''if you want to include all feature classes, regardless of wheteher they're in a dataset.'''
#FDlist = [''] + FDlist if FDlist is not None else [] 

for FD in FDlist:
    FClist= arcpy.ListFeatureClasses(feature_dataset = FD)
    for FC in FClist:
        print(FC)
        if not (field1 in arcpy.ListFields(FC) and (field2 in arcpy.ListFields(FC))):
            FC = arcpy.management.AddField(FC, field1, "DOUBLE",field_alias = "Lat")
            FC = arcpy.management.AddField(FC, field2, "DOUBLE",field_alias = "Long")
