One tiny tweak...
class User():
You don't need the parens after User. You don;t have any superclasses
so they do nothing. Python convention for an empty parent list is just
to leave the parens off:

A simple question from a newbie, in response to this surprise.
Is it not helpful to always put (object) as the parent, if the class is
not itself a sub-class?
The answer differs between Python 2 and 3. In Python 3
class C: # preferred in Python 3
pass
and
class C(object):
pass
are the same, so there is no point adding the explicit object inheritance.
In Python 2 however
class C:
pass
will create a "classic class" whereas
class C(object): # preferred in Python 2
pass
is a "newstyle class". The most notable difference between these is that
properties work correctly only with newstyle classes. Therefore making all
your classes "newstyle" is a good idea.
And while I am writing, what does OP stand for in this list?
Original Poster, as Leam says.

Thanks Peter, most helpful.
I was taught with Python 2.7, so now I understand the advice.
