Hi,
I'm familiar with static method concept, but what is the class method?
how it does differ from static method? when to use it?

class M:
def method(cls, x):

method = classmethod(method)

Thank you for your time.
Firstly, don't use method = classmethod(method). Decorators are far
better. The following code has the same effect:
class M:
@classmethod
def method(cls, x):
pass
Far more readable, right?
Yes, but will only work with Python >= 2.4. There are cases where you
want to keep compatibility with Python 2.3...
Class methods are useful if you've got lots of inheritance happening.
The first argument passed in is the class calling the method. Handy
for a mix-in: it can add methods affecting the actual class it's mixed
into, rather than messing with the mix-in itself.
I'm not sure I get your point here.
As far as I'm concerned, classmethods are useful anywhere you need to
work on the class object itself.
