有没有办法在不重新启动整个py文件的情况下停止并启动discord.py机器人？

import discord

bot = discord.Bot()

@bot.event
async def on_ready():
    print('Bot is ready')

@bot.command()
async def hello(ctx):
    await ctx.send('Hello!')

# 启动机器人
bot.run('YOUR_BOT_TOKEN')

@bot.command()
async def stop(ctx):
    await ctx.send('Stopping bot...')
    await bot.close()

import discord
import signal
import sys

bot = discord.Bot()

@bot.event
async def on_ready():
    print('Bot is ready')

@bot.command()
async def hello(ctx):
    await ctx.send('Hello!')

def stop_bot(signal, frame):
    print('Stopping bot...')
    bot.loop.run_until_complete(bot.close())
    sys.exit(0)

# 注册信号处理函数
signal.signal(signal.SIGINT, stop_bot)

# 启动机器人
bot.run('YOUR_BOT_TOKEN')
