如何避免在asyncio (telethon)中使用"global“？

class SharedState:
    def __init__(self):
        self.shared_data = None

    def set_data(self, data):
        self.shared_data = data

    def get_data(self):
        return self.shared_data

state = SharedState()

async def coroutine1():
    state.set_data("Hello")
    await asyncio.sleep(1)
    print(state.get_data())  # 输出: Hello

async def coroutine2():
    state.set_data("World")
    await asyncio.sleep(1)
    print(state.get_data())  # 输出: World

async def main():
    await asyncio.gather(coroutine1(), coroutine2())

asyncio.run(main())

import asyncio
import contextvars

shared_data = contextvars.ContextVar('shared_data')

async def coroutine1():
    shared_data.set("Hello")
    await asyncio.sleep(1)
    print(shared_data.get())  # 输出: Hello

async def coroutine2():
    shared_data.set("World")
    await asyncio.sleep(1)
    print(shared_data.get())  # 输出: World

async def main():
    await asyncio.gather(coroutine1(), coroutine2())

asyncio.run(main())
