写多任务异步协程出了点问题，但报错信息很不对劲，找不到问题所在
以下是代码：
import asyncio
import time
async def syy1():
print("syy1 1")
await asyncio.sleep(3)
print("syy1 2")
async def syy2():
print("syy2 1")
await asyncio.sleep(2)
print("syy2 2")
async def syy3():
print("syy3 1")
await asyncio.sleep(1)
print("syy3 2")
if __name__ == '__main__':
# 生成三个异步协程对象
s1=syy1()
s2=syy2()
s3=syy3()
tasks=[s1,s2,s3]
#记录时间
t1=time.time()
asyncio.run(asyncio.wait(tasks))
t2=time.time()
print(t2-t1)
接着是报错信息：
Traceback (most recent call last):
File "C:/Users/Administrator/Desktop/py爬虫入门/线程，进程和协程/多任务异步协程.py", line 31, in <module>
asyncio.run(asyncio.wait(tasks))
