if嵌套这么多？是要当老师吗！

我将对代码进行进一步优化，使其更加简洁、清晰，并添加必要的注释以便更好地理解。以下是优化后的代码：

`### 优化后的代码

import requests
import itchat
from itchat.content import *
import random
import re
import os
import time

全局变量

msg_dict = {} # 用于存储消息记录
flag = 0 # 表情包斗图标志
sj = None # 上次斗图时间
isrun = "已停止！" # 机器人运行状态
use_info = "这是一个微信机器人，支持自动回复和表情包斗图。" # 机器人使用说明

获取机器人回复

def get_response(msg):
url = "http://api.example.com/response" # 替换为实际的请求 URL
headers = {
'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/79.0.3945.79 Safari/537.36'
}
try:
r = requests.get(url, headers=headers, params={"msg": msg})
response = re.findall(r'"content":"(.*?)"', r.text)[0].replace('\r\n', '')
return response
except Exception as e:
print(f"Error in get_response: {e}")
return "抱歉，我无法理解你的问题。"

获取自定义回复词汇

def get_words():
words_file = './words.txt'
if os.path.exists(words_file):
with open(words_file, 'r', encoding='utf-8') as f:
return f.read().splitlines()
return []

获取好友信息

def get_friendname():
friends = itchat.get_friends(update=True)
return {friend['UserName']: {'nickname': friend['NickName'], 'remarkname': friend['RemarkName']} for friend in friends[1:]}

获取群组信息

def get_username():
chatrooms = itchat.get_chatrooms(update=True)
all_user_name = [chatroom['UserName'] for chatroom in chatrooms]
vip_file = './vip.txt'
vip = []
if os.path.exists(vip_file):
with open(vip_file, 'r', encoding='utf-8') as f:
vip = f.read().splitlines()
user_name = [chatroom['UserName'] for chatroom in chatrooms if chatroom['NickName'] in vip]
return all_user_name, user_name, vip
