hi, all:
我在國外的某個blog上看到一篇文章：
http://tinyurl.com/8t73xp
裡面的一段程式碼：
>>> class Foo(object):
... def __init__(self, name='', stuff=[]):
... self.name = name
... self.stuff = stuff
...
... def add_stuff(self, gadget):
... self.stuff.append(gadget)
...
>>> f = Foo()
>>> f.add_stuff('tree')
>>> f.stuff
['tree']
>>> g = Foo()
>>> g.stuff
['tree']
這結果跟我之前學的OOP有些不同..沒實際執行一次，我會以為g.stuff應該是[]
雖然它底下有說原因：
What happens here is that default values for arguments are created by Python
only once per each function/method, at the time of its definition.
小的是python新手，看不太懂真正原因，不知道可否有前輩幫忙解說一下呢?
感謝!
