Getting name of subtype field in feature class in ArcPy?

Question

I have a geodatabase with many feature classes. Some of the feature classes have subtype fields. Their names vary feature class by feature class. I now want to find the names of those subtype fields. What I have so far is:

for fc in arcpy.ListFeatureClasses("*","",dataset):
 subtypefields = arcpy.da.ListSubtypes(fc)
 for subtype in subtypefields:

Now, I don't know how to continue from here.

There is a good example in the documentation. Adapted for your purposes:

for fc in arcpy.ListFeatureClasses("*","",dataset):
 subtypes = arcpy.da.ListSubtypes(fc)
 for stcode, stdict in subtypes.iteritems():
 print('Code: {0}'.format(stcode))
 for stkey in stdict.iterkeys():
 if stkey == 'FieldValues':
 print('Fields:')
 fields = stdict[stkey]
 for field, fieldvals in fields.iteritems(): 
 print(' --Field name: {0}'.format(field))
 print(' --Field default value: {0}'.format(fieldvals[0]))
 if not fieldvals[1] is None:
 print(' --Domain name: {0}'.format(fieldvals[1].name))
 else: 
 print('{0}: {1}'.format(stkey, stdict[stkey]))
