Using a coroutine as decorator

Question

in this scenario:

async def foo(f):
    async def wrapper(*args, **kwargs):
        return f(*args, **kwargs)
    return wrapper

@foo
async def boo(*args, **kwa         


        

Answer 1

Here is an alternate approach using the decorator library (i.e. pip install decorator first):

import asyncio

import decorator


@decorator.decorator
async def decorate_coro(coro, *args, **kwargs):
    try:
        res = await coro(*args, **kwargs)
    except Exception as e:
        print(e)
    else:
        print(res)


@decorate_coro
async def f():
    return 42


@decorate_coro
async def g():
    return 1 / 0


async def main():
    return await asyncio.gather(f(), g())

if __name__ == '__main__':
    asyncio.run(main())

Output:

42
division by zero
