优化这段代码 def listbox_option_list(self, value: str) -> None: temp_list = [] ValueList = self.driver.find_elements(By.XPATH, '//ul[@role="listbox"]/li[@role="option"]') for valuemeta in ValueList: temp_list.append(valuemeta.text) value_list = [i for i in temp_list if i != ""] print(value_list) try: for value_meta in ValueList: if value in value_list: if value_meta.text == value: value_meta.click() if value not in value_list: ValueList[-1].click() break except: pass

可以尝试使用列表推导式简化代码，同时可以使用更加直观的变量名来提高代码可读性。以下是优化后的代码：

def listbox_option_list(self, value: str) -> None:
value_list = [val.text for val in self.driver.find_elements(By.XPATH, '//ul[@role="listbox"]/li[@role="option"]') if val.text != ""]
print(value_list)
try:
for value_meta in self.driver.find_elements(By.XPATH, '//ul[@role="listbox"]/li[@role="option"]'):
if value in value_list:
if value_meta.text == value:
value_meta.click()
else:
self.driver.find_elements(By.XPATH, '//ul[@role="listbox"]/li[@role="option"]')[-1].click()
break
except:
pass

优化代码 def listbox_option_list(self, value: str) -> None: temp_list = [] ValueList = self.driver.find_elements(By.XPATH, '//ul[@role="listbox"]/li[@role="option"]') for valuemeta in ValueList: temp_list.append(valuemeta.text) value_list = [i for i in temp_list if i != ""] print(value_list) try: for value_meta in ValueList: if value in value_list: if value_meta.text == value: value_meta.click() if value not in value_list: ValueList[-1].click() break except: pass

这是一个关于优化代码的问题，我可以回答。这段代码中，可以将第一个 for 循环中的 temp_list 替换为列表推导式，以提高效率。同时，可以将 try-except 块中的 except 块中的 pass 替换为具体的异常处理代码，以便更好地处理异常情况。

在这段代码中，IP地址及端口号是在 ChatClient 类的初始化函数中进行设置的：

def __init__(self, host, port):
    self.sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    self.sock.connect((host, port))
    self.buffer_size = 1024

在这里，你可以将 `host` 参数设置为你想要连接的服务器的 IP 地址，将 `port` 参数设置为服务器的端口号。在 ChatApp 类的 `connect` 函数中，调用了 ChatClient 类来连接服务器：

def connect(self):
    self.chat_client = ChatClient('localhost', 5000)
    self.connect_button.config(state=tk.DISABLED)
    self.disconnect_button.config(state=tk.NORMAL)
    threading.Thread(target=self.recv_msg).start()

在这里，`ChatClient('localhost', 5000)` 表示连接到本地主机的 5000 端口。如果你想连接到其他主机的端口，则需要将 `'localhost'` 替换为该主机的 IP 地址，将 `5000` 替换为该主机的端口号。
