Hi,
I want to define a special class which groups functions, like:
class Greepting(FuncGroup):
def hello(): # no self, no @staticmethod!
print("Hello!")
def goodbye(): # no self, no @staticmethod!
print("Good Bye!")
Geeting.hello(): #=> "Hello!"
Geeting.goodbye(): #=> "Good Bye!"
I tried the following code which converts instance mthods into
static method automatically, but I don't get result what I want.
(python 2.5.5)
import sys
from types import FunctionType
class MetaClass(type):
def __init__(cls, name, bases, dct):
## converts instance methods to static methods automatically
for k in dct.keys():
v = dct[k]
if isinstance(v, FunctionType):
dct[k] = staticmethod(v)
print("*** debug: dct[%r] = %r" % (k, dct[k]))
#=> <staticmethod object at 0x100378d38>
class FuncGroup(object):
__metaclass__ = MetaClass
class Greeting(FuncGroup):
def hello():
print("Hello!")
def goodbye():
print("Good Bye!")
print("*** type(Greeting.hello)=%r" % type(Greeting.hello)
#=> <type 'instancemthod'>
print("*** type(Greeting.goodbye)=%r" % type(Greeting.goodbye)
#=> <type 'instancemthod'>
Could you give me advice?
