python协程问题
我是Windows系统，输入的代码如下，想问问该怎么解决这个问题呀import asyncio
async def fun1():
print('I am INsider1')
await asyncio.sleep(1)
print('1finished')
async def fun2():
print("I am INsider2")
await asyncio.sleep(2)
print("2finished")
async def fun3():
print("I am INsider3")
await asyncio.sleep(3)
print("3finished")
if __name__ == '__main__':
f1 = fun1()
f2 = fun2()
f3 = fun3()
fs =
event_loop = asyncio.get_event_loop()
event_loop.run_until_complete(asyncio.wait(fs))
报错如下：
raise TypeError("Passing coroutines is forbidden, use tasks explicitly.")
TypeError: Passing coroutines is forbidden, use tasks explicitly.
sys:1: RuntimeWarning: coroutine 'fun1' was never awaited
sys:1: RuntimeWarning: coroutine 'fun2' was never awaited
sys:1: RuntimeWarning: coroutine 'fun3' was never awaited
从您的错误提示来看，问题出在您将协程函数直接传递给`asyncio.wait()`。解决这个问题的方法是使用`asyncio.create_task()`将协程函数包装为任务对象，然后传递这些任务对象给`asyncio.wait()`。请修改您的代码如下：
import asyncio
async def fun1():
print('I am INsider1')
await asyncio.sleep(1)
print('1finished')
async def fun2():
print("I am INsider2")
await asyncio.sleep(2)
print("2finished")
async def fun3():
print("I am INsider3")
await asyncio.sleep(3)
print("3finished")
if __name__ == '__main__':
f1 = fun1()
f2 = fun2()
f3 = fun3()
fs =
event_loop = asyncio.get_event_loop()
# 将协程对象包装为任务对象
tasks =
# 将任务对象传递给 asyncio.wait
event_loop.run_until_complete(asyncio.wait(tasks))
现在，您的代码应该可以正常运行并输出预期结果。另外，从Python 3.7开始，可以使用`asyncio.run()`简化事件循环的创建和关闭操作，不过这需要将您的代码封装在一个异步函数中。如果您的Python版本 >= 3.7，可以考虑将代码改成如下：
import asyncio
async def fun1():
print('I am INsider1')
await asyncio.sleep(1)
print('1finished')
async def fun2():
print("I am INsider2")
await asyncio.sleep(2)
print("2finished")
async def fun3():
print("I am INsider3")
await asyncio.sleep(3)
print("3finished")
async def main():
f1 = fun1()
f2 = fun2()
f3 = fun3()
fs =
tasks =
await asyncio.wait(tasks)
if __name__ == '__main__':
asyncio.run(main())
这样，代码会更简洁。
