def A(event):
B(event)
return "something"
def B(event)
return event
Let's say I have a function like the one above, how do make function A return its output and not wait for function B. The output of A does not depend on function B but function B depends on the input of function A.
In your example most easy way to do it is to run B in a thread. For example:
import time
from concurrent.futures import ThreadPoolExecutor
executor = ThreadPoolExecutor(max_workers=1)
def A():
executor.submit(B)
print("Hi from A")
def B():
time.sleep(1)
print("Hi from B")
if __name__ == '__main__':
A()
If you want to do it using asyncio, you should wrap A and B to be coroutines and use asyncio.Task. Note however that unless B is I/O related it wouldn't be possible to make it coroutine without using thread. Here's more detailed explanation.
