Very simple question on the preferred coding style. I frequently write
classes that have some data members initialized to immutable values.
For example:
class Test(object):
def __init__(self):
self.some_value = 0
self.another_value = None
Similar effect can be achieved by defining some_value and
another_value for the entire class, like so:
class Test(object):
some_value = 0
another_value = None
The advantage of doing this is that the assignments are evaluated once
and thus the creation of that class is a bit faster. Access is still
performed through self.some_value and self.another_value. Is there a
reason to prefer the first style over the second?
