的Python：实例没有属性 'sendAMail'

我刚刚得到的错误：的Python：实例没有属性 'sendAMail'

AttributeError: SecondLife instance has no attribute 'sendAMail'

的哪些错误？（我检查了格式化，这不是错误我检查了语法，也没有错误。）

脚本发生什么是一个网址打开与饼干，我想从它的一些信息。

对我的作品：从实例中打印出self.sendAMail给

<bound method SecondLife.sendAMail of <__main__.SecondLife instance at 0x101d91e18>>

我认为这是一个格式问题，虽然。如果我复制并粘贴代码并查看空白，我会看到空格和制表符混合使用。特别是：

In [20]: [line for line in d if 'def' in line] 
Out[20]: 
['  def __init__(self, usernames, password):\n', 
' \tdef sendAMail(self, smtp_server, user, password, listener, subject, text):\n', 
'  def login(self):\n', 
'  def friends_online(self):\n']

def sendAMail前\t看起来非常可疑。我75％确定不一致的空白是导致问题的原因。尝试使用python -tt scriptname.py运行脚本，这会导致标签使用不一致的错误。

如果事实证明是一个混合使用空白的错误，这将是一个OP永远不会忘记的教训。这就是为什么源代码在使用空格时应该是一致的。 – inspectorG4dget 2012-07-09 00:31:10

@DSM也为我工作在2.7。 – 2012-07-09 01:49:36

感谢这是一个空白的错误！ :) – Furtano 2012-07-09 12:31:14
