我只是得到错误：

AttributeError: SecondLife instance has no attribute 'sendAMail'

怎么了？（我检查了格式，这不是错误。我检查了语法，也没有错误。）

脚本中发生的是一个 url 用 cookie 打开，我想从中获取一些信息。

import urllib2, cookielib, re
import ClientForm
import re
import smtplib

kurse = ['Entwicklung von Multimediasystemen', 'Computergrafik', 'Gestaltung von Multimediasystemen', 'Verteilte Systeme']

class SecondLife:

    def __init__(self, usernames, password):
        self.username = usernames
        self.password = password
        self.url = 'https://lsf.htw-berlin.de/qisserver/rds?state=user&type=0&application=QISPOS'

        cookiejar = cookielib.LWPCookieJar()
        cookiejar = urllib2.HTTPCookieProcessor(cookiejar)
        # debugger = urllib2.HTTPHandler(debuglevel=1)

        opener = urllib2.build_opener(cookiejar)
        urllib2.install_opener(opener)

    def sendAMail(self, smtp_server, user, password, listener, subject, text):
        smtp = smtplib.SMTP(smtp_server)
        smtp.starttls()
        smtp.login(user,password)
        msg = "SUBJECT: " + subject + "\n\n" + text
        smtp.sendmail("bln.schade@gmail.com", listener, msg)
        smtp.quit()

    def login(self):
        response = urllib2.urlopen(self.url)
        forms = ClientForm.ParseResponse(response, backwards_compat=False)

        # forms[0] is 'GET', forms[1] is 'POST'
        form = forms[0]

        try:
            form['username'] = self.username
            form['password'] = self.password
        except Exception, e:
            print 'The following error occured: \n"%s"' % e
            print
            print 'A good idea is to open a browser and see if you can log in from there.'
            print 'URL:', self.url

            exit()

        self.page = urllib2.urlopen(form.click('submit')).read()

    def friends_online(self):

        match = re.search(r"asi=\w*\d*\"", self.page)

        if match:

            final_asi = re.sub("asi=", "", final)
            final_asi = re.sub("\"", "", final_asi)

            leistungsstand = urllib2.urlopen(leistungsstand_url).read()

对我有用：self.sendAMail从实例中打印出来

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

不过，我认为这是格式问题。如果我复制并粘贴您的代码并查看空格，我会看到空格和制表符的混合使用。尤其是：

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']

\t之前def sendAMail看起来很可疑。我 75% 确定不一致的空格是导致问题的原因。尝试使用 运行您的脚本python -tt scriptname.py，这将引发关于标签使用不一致的错误。
