如何编写异步执行任务的递归函数？
How to write a recursive function which performs tasks asynchronously?
如何在python中创建递归协程函数？
import asyncio
def fetch_url(x):
if isinstance(x, list):
return map(fetch_url, x)
else:
return parsed_url(x)
即调用double(10)时函数同步执行，调用double([2,3,4])时异步执行
如果 "would execute asynchronously" 你的意思是 "in parallel"，试试这个：
async def fetch_url(x):
if isinstance(x, list):
return await asyncio.gather(*[fetch_url(url) for url in x])
return parsed_url(x)
