Issue
I get this error:
D:\pythonstuff\demo.py:28: DeprecationWarning: The explicit passing of coroutine objects to asyncio.wait() is deprecated since Python 3.8, and scheduled for removal in Python 3.11. await asyncio.wait([
Waited 1 second!
Waited 5 second!
Time passed: 0hour:0min:5secProcess finished with exit code 0
When I run the code:
import asyncio
import time
class class1():
async def function_inside_class(self):
await asyncio.sleep(1)
print("Waited 1 second!")
async def function_inside_class2(self):
await asyncio.sleep(5)
print("Waited 5 second!")
def tic():
global _start_time
_start_time = time.time()
def tac():
t_sec = round(time.time() - _start_time)
(t_min, t_sec) = divmod(t_sec,60)
(t_hour,t_min) = divmod(t_min,60)
print('Time passed: {}hour:{}min:{}sec'.format(t_hour,t_min,t_sec))
object = class1()
async def main():
tic()
await asyncio.wait([
object.function_inside_class(),
object.function_inside_class2()
])
tac()
loop = asyncio.get_event_loop()
loop.run_until_complete(main())
loop.close()
Are there any good alternatives to asyncio.wait
? I don't want a warning in console every time I launch my application.
Edit: I don't want to just hide the error, that's bad practice, and I'm looking for other ways to do the same or a similar thing, not another async library to restore the old functionality.
Solution
You can just call it this way as it recommends in the docs here
Example from the docs:
async def foo():
return 42
task = asyncio.create_task(foo())
done, pending = await asyncio.wait({task})
So your code would become:
await asyncio.wait([
asyncio.create_task(object.function_inside_class()),
asyncio.create_task(object.function_inside_class2())
])
