My personal experience is that I almost *never* want a staticmethod.
The things that I would have written as a staticmethod in Java I simply
write as a module-level function in Python.
I do occasionally used classmethods though to build alternate
constructors. I recently had a class with a constructor that looked like:
class C(object):
def __init__(self, *args):
...
I already had code working with this constructor, but I needed to add an
optional 'index' parameter. I found the clearest way to do this was
something like:
class C(object):
def __init__(self, *args):
...
@classmethod
def indexed(cls, index, *args):
...
obj = cls(*args)
obj.index = index
...
return obj
Then the classes that needed the 'index' parameter simply use
C.indexed() as the constructor instead of C().
