way to define static method

[Eric CHAO]

Thanks a lot.

Because I found a solution about static method from
http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/52304

And that's a little bit difficult to understand.

# direct, naive approach -- doesn't work...:
class Class1:
   def static1(name):
       print "Hello",name

# ...but now, a call such as:
Class1.static1("John")
# will fail with a TypeError, as 'static1' has become
# an unbound-method object, not a plain function.

# This is easy to solve with a simple tiny wrapper:
class Callable:
   def __init__(self, anycallable):
       self.__call__ = anycallable

# toy-example usage:
class Class2:
   def static2(name):
       print "Hi there",name
   static2 = Callable(static2)

# now, a call such as:
Class2.static2("Peter")
# works just fine, and as-expected
