这个为什么报错呀，想了半天没有明白
import asyncioimport time
async def func1():
print("你好啊，我是1")
await asyncio.sleep(3)
print("你好啊，我是1")
async def func2():
print("你好啊，我是2")
await asyncio.sleep(2)
print("你好啊，我是2")
async def func3():
print("你好啊，我是3")
await asyncio.sleep(4)
print("你好啊，我是3")
if __name__ == '__main__':
f1 = func1()# 此时的函数是异步协程函数。此时函数执行得到的是一个协程对象
f2 = func2()
f3 = func3()
# asyncio.run(f1)#协程程序运行需要asyncio模块的支持
tasks = [
f1, f2, f3
]
t1 = time.time()
# 一次性启动多个任务(协程)
asyncio.run(asyncio.wait(tasks))
t2 = time.time()
print(t2 - t1)
这个python3.11的问题，python3.11直接传一个协程对象会报错，得传 task

参考代码：
import asyncio
import time
async def func1():
print("你好啊，我是1")
await asyncio.sleep(3)
print("你好啊，我是1")
async def func2():
print("你好啊，我是2")
await asyncio.sleep(2)
print("你好啊，我是2")
async def func3():
print("你好啊，我是3")
await asyncio.sleep(4)
print("你好啊，我是3")
if __name__ == '__main__':
f1 = func1()# 此时的函数是异步协程函数。此时函数执行得到的是一个协程对象
f2 = func2()
f3 = func3()
t1 = time.time()
loop = asyncio.new_event_loop()
tasks = [
loop.create_task(i) for i in
]
loop.run_until_complete(asyncio.wait(tasks))
t2 = time.time()
print(t2 - t1)
我运行没有问题 我这里正常运行
