Following Pan gis's suggestion, after running the Remove Domain From Field tool from the ArcToolbox in ArcMap, I clicked on the Geoprocessing tab, then copied the Results as a Python snippet. This will show how ArcMap populates the tool's parameters.
arcpy.RemoveDomainFromField_management(in_table="PW_Conduit_Wire",
field_name="FLOOR_ID",
subtype_code="'1: Earth NET';'2: ELTW';'3: LTW';'4: Conduit'")
After checking the ListSubtypes documentation, I came up with the following code which should remove the domains from the features using subtypes.
import arcpy
gdb = r'C:\Path\To\COBW_Power.gdb'
arcpy.env.workspace = gdb
domains = ['CD_Level','CD_FittingDiameter','CD_FittingMaterial',
'CD_Diameter','CD_Material','CD_Ownership','CD_Parcel ID']
for fds in arcpy.ListDatasets('','Feature'):
print "DS: {}".format(fds)
for fc in arcpy.ListFeatureClasses("*","",fds):
print "\tFC: {}".format(fc)
subtypes = arcpy.da.ListSubtypes(fc)
for stcode, stdict in list(subtypes.items()):
for stkey in list(stdict.keys()):
if not stdict['SubtypeField'] == '':
st_code = "'{}: {}'".format(stcode, stdict['Name'])
if stkey == 'FieldValues':
fields = stdict[stkey]
for field, fieldvals in list(fields.items()):
if not fieldvals[1] is None:
if fieldvals[1].name in domains:
print("\t\t{} domain deleted from field {} in subtype {}".format(fieldvals[1].name, field, st_code))
arcpy.RemoveDomainFromField_management(in_table=fc, field_name=field, subtype_code=st_code)
print "Done."
My previous code should remove the remaining domains from features not using subtypes.
=====
Edit: After some additional thought, here is a version that will remove domains from fields whether using subtypes or not. Basically, I added an else on line 21 to pass RemoveDomainFromField a "#" if the feature doesn't use a domain. The indentation, starting at line 23, was changed as a result.
import arcpy
gdb = r'C:\Path\To\COBW_Power.gdb'
arcpy.env.workspace = gdb
domains = ['CD_Level','CD_FittingDiameter','CD_FittingMaterial',
'CD_Diameter','CD_Material','CD_Ownership','CD_Parcel ID']
for fds in arcpy.ListDatasets('','Feature'):
print "DS: {}".format(fds)
for fc in arcpy.ListFeatureClasses("*","",fds):
print "\tFC: {}".format(fc)
subtypes = arcpy.da.ListSubtypes(fc)
for stcode, stdict in list(subtypes.items()):
for stkey in list(stdict.keys()):
if not stdict['SubtypeField'] == '':
st_code = "'{}: {}'".format(stcode, stdict['Name'])
else:
st_code = "
if stkey == 'FieldValues':
fields = stdict[stkey]
for field, fieldvals in list(fields.items()):
if not fieldvals[1] is None:
if fieldvals[1].name in domains:
print("\t\t{} domain removed from field {} using subtype {}".format(fieldvals[1].name, field, st_code))
arcpy.RemoveDomainFromField_management(in_table=fc, field_name=field, subtype_code=st_code)
print "Done."
