Question

我想要一个与以下类似的代码：

async def func(user_response):
 #does_something

while condition:
 #waits for a response from the user
 #await func(response from user)

但是，我希望它在函数执行时等待用户的另一个响应。

我试过了：

async def func(user_response):
 #does_something

while condition:
 #waits for a response from the user
 #asyncio.create_task(response from user)

然而，我发现的问题是，如果用户响应两次，这两个功能将同时执行（当我基本上是排队时）。

异步任务是否可以排队

是的，您可以为此使用 asyncio.Queue：

async def func(user_response):
    #does_something

async def worker(queue):
    while True:
        user_response = await queue.get()
        await func(user_response)

async def main():
    queue = asyncio.Queue()
    # spawn the worker in the "background"
    asyncio.create_task(worker(queue))
    while condition:
        #waits for a response from the user
        # enqueue the response to be handled by the worker
        await queue.put(user_response)

异步任务可以排队吗
