使用成员变量的Python AttributeError

Question

我遇到了Python在访问变量时抛出AttributeError的问题。

代码如下，为了清晰起见进行了编辑。

class mycollection(object): 
    """ 
    Collection of stuff. 
    """ 
    #"compile-time" define class variables. 
    __slots__ = ["stuff_list"] 

    def __init__(self): 
     self.stuff_list = [] 

    def add_stuff(self, stuff): 
     self.stuff_list.append(stuff) 


#later on.. 
collection = mycollection() 
stuff = stuff() 
collection.add_stuff(stuff) 

生成此错误。

Traceback (most recent call last): 
    File "", line 210, in <module> 
    main() 
    File "", line 206, in main 
    thestuff = load_file(inputfile, filetype) 
    File "pyyft.py", line 121, in load_file 
    collection.add_stuff(stuff) 
    File "pyyft.py", line 55, in add_test 
    self.stuff_list.append(stuff) 
AttributeError: stuff_list 

通过documentation检查，我不明白为什么这个错误出现。

Answer 1

__ini__应该__init__

Answer 2

这是不是可以 “更Python”？

collection.stuff_list.append（test_stuff）
