If you don't care about being able to change the attributes
dynamically, define the `__slots__` of your class, and then you can
use
return '\n'.join('%s: %s' % (name, getattr(self, name)) for name in
self.__slots__)
Calling `getattr` is probably more Pythonic than looking things up in
`__dict__`, string formatting can take care of "casting" (converting,
really) for you, and the nested `join` is really overkill :) Anyway
the main point is that `__slots__` is a list, and thus has a defined
order.

Depending. Sometimes you want them to behave the same way. Since
functions are objects, this is as simple as `__repr__ = __str__`. :)
p.s. Is Python seeing a lot of use at Ubisoft or is this just for
personal interest (or perhaps both)?
