我正在学习python，因为我需要它，所以请坚持下去，因为这段代码会很混乱！...
所以我使用glade为我的客户端twitch irc chat bot创建了一个gui，并在工具栏中创建了这个切换按钮：
<object class="GtkToggleToolButton" id="tool_deploy_toggle">
<property name="use_action_appearance">False</property>
<property name="visible">True</property>
<property name="can_focus">False</property>
<property name="label" translatable="yes">Connect</property>
<property name="use_underline">True</property>
<property name="stock_id">gtk-jump-to</property>
<signal name="toggled" handler="on_tool_deploy_toggle_toggled" swapped="no"/>
</object>
我希望这个切换按钮打开一个套接字，并在按钮向下“切换”时将机器人部署到抽搐irc聊天中（并且还可以看到一些定义和加载内容）：
irc = botOpenSocket()
joinRoom(irc)
readbuffer = ""
irc.send("CAP REQ :twitch.tv/membership\r\n")
irc.send("CAP REQ :twitch.tv/commands\r\n")
irc.send("CAP REQ :twitch.tv/tags\r\n")
try:
with file("commands.json","r") as commandsDatabase:
commands = json.load(commandsDatabase)
except IOError:
commands = {}
with file("commands.json","w") as commandsDatabase:
json.dump(commands, commandsDatabase)
globalcommands = {"spank": True}
moderatorcommands = {"addcom": True, "delcom": True}
stringspace = " "
nothing = ""
now = time.time()
cooldown = lambda: time.time() > now + 1
然后我希望它继续循环这段代码（忽略它们用葡萄牙语的评论）（也是的，我知道我的代码不是最好的，我只是学习）：
while True:
readbuffer = readbuffer + irc.recv(1024)
temp = string.split(readbuffer, "\n")
readbuffer = temp.pop()
for line in temp:

globalcommandskeys = str(globalcommands.keys()).replace("[", "").replace("]", "")

try:

break
try:
replacing = commands[command]
sendMessage(irc, replacing.replace("$target", target))
now = time.time()
cooldown = lambda: time.time() > now + 10
except KeyError:
break
break
然后最后当按钮“向上”切换时我想关闭套接字以便机器人离开irc服务器：
irc.close()
我希望能够在不关闭和重新打开脚本的情况下完成上述所有事情。
所以问题是我不能这样做。
如果我放入主脚本（连接来自GUI的按钮信号的脚本），它将破坏gtk主循环，GUI将崩溃。
我试过使用线程，但我似乎不理解它们。
所以这就是我到达这里寻求帮助的原因。
PLS HALP ME，我无法入睡，因为我一直在想这个!!!
答案 0 :(得分：0)
状态更新我对线程进行了更多的研究，并从另一个stackoverflow帖子中获得了一个线程示例并使其正常工作！
我创建了这个线程（请注意，在joinRoom(irc, self)之后，如果连接成功，套接字被设置为非阻塞，否则它会loop.clear()使它永远不会进入机器人主循环并直接进入irc.close()）：

定义它：

连接处理程序：
