✅
list_display
can accept a callable, so you can do this:
class MyModelAdmin(admin.ModelAdmin):
list_display = ('get_sub_title',)
def get_sub_title(self, obj):
if obj.sub_title:
return obj.sub_title
else:
return 'Not Available'
get_sub_title.short_description = 'Subtitle'
The docs provide several other options for providing a callable.

It would be better if you use empty_value_display
empty_value_display
This attribute overrides the default display value for record’s fields that are empty (None, empty string, etc.). The default value is – (a dash).
class AuthorAdmin(admin.ModelAdmin):
list_display = ('sub_title',)
sub_title.empty_value_display = 'Not Available'
This is for django >= 1.9
