Question

我将从＆＃34开始;我不熟悉Python＆＃34;。我尝试为我的频道更改扭曲的默认ircbot脚本，但我无法让re.match或re.search正常工作。

例如，这有效：

prompt = ("%s" % self.nickname)
prompt1 = ("%s:" % self.nickname)
prompt2 = ("%s," % self.nickname)

if msg == (prompt1 + " whoareyou?") or msg == (prompt2 + " who are you?") or msg == (prompt1 + " whoareyou") or msg == (prompt2 + " who are you"):

这个也是

if msg == (prompt1 + " help") or msg == (prompt2 + " help"):

但是这两个条件在机器人上不起作用（但是它们在本地脚本上工作）：

if re.search(r'%s[:,] help' % self.nickname, msg):

elif re.search(r'%s[:,] who ?are ?you?' % self.nickname, msg):

可以找到以前版本的未使用re.search的脚本here

我找到了导致问题的原因。 Twisted包含一个逻辑来处理机器人的昵称冲突。它在名称的末尾添加^：

# For fun, override the method that determines how a nickname is changed on
# collisions. The default method appends an underscore.
def alterCollidedNick(self, nickname):
    """
    Generate an altered version of a nickname that caused a collision in an
    effort to create an unused related name for subsequent registration.
    """
    return nickname + '^'

这导致我的机器人昵称以nickname^结尾，并且因为我使用%s添加昵称变量作为正则表达式的一部分，它将^解释为修饰符。

if re.search(r'%s[:,] help' % self.nickname, msg):

对此：

if re.search(r'nickname^[:,] help', msg):

无法将正则表达式与Twisted Framework ircbot上的re.search相匹配
