Create a python coroutine that will provide logging as a decorator to a method. Make sure to provide an example.

Sure, here's a simple example of a decorator function that creates a coroutine and provides logging. It logs the method name, arguments, and the result of calling the method.

```python
import logging
import concurrent.futures

def log_coroutine(func):
    async def wrapper(*args, **kwargs):
        logging.debug(f'Entering {func.__name__} with args {args} and kwargs {kwargs}')
        try:
            result = await func(*args, **kwargs)
            logging.debug(f'Finished {func.__name__}, return value: {result}')
            return result
        except Exception as e:
            logging.error(f'Error in {func.__name__}: {e}')
            raise

    coroutine = concurrent.futures.CoroutineType(func)
    return wrapper

@log_coroutine
async def my_method(a, b):
    await asyncio.sleep(1)
    return a + b

async def test():
    coro = my_method(2, 3)
    result = await coro
    print(result)

asyncio.run(test())
```

In this example, the `log_coroutine` decorator is defined to wrap any method marked with `@log_coroutine`. It logs the method name, arguments, and the result of calling the method. The `asyncio.sleep` function is used here as a way to wait for a certain duration of time just to keep the coroutine running.

After defining the `log_coroutine` decorator, defining the `my_method` function with this decorator. The `test` method runs the wrapped method. The `asyncio.run` calls the `test` method and waits for the coroutine to end.

Sure, I can help with that. Python coroutines are a bit different from decorators, but we can use Python's async/await syntax to create a coroutine that can be used in a decorator-like fashion. Here's an example:

```python
import asyncio
import functools
import logging

logging.basicConfig(level=logging.INFO)
logger = logging.getLogger(__name__)

def coroutine_decorator(func):
    @functools.wraps(func)
    async def wrapper(*args, **kwargs):
        logger.info(f"Starting function: {func.__name__}")
        result = await func(*args, **kwargs)
        logger.info(f"Finished function: {func.__name__}")
        return result
    return wrapper

@coroutine_decorator
async def example_function():
    await asyncio.sleep(1)
    return "Hello, world!"

async def main():
    result = await example_function()
    print(result)

asyncio.run(main())
```

In this example, `coroutine_decorator` is a decorator that logs the start and finish of the decorated function. The decorated function, `example_function`, is a coroutine that sleeps for 1 second and then returns a string. The `main` function runs the `example_function` coroutine and prints the result.

When you run this code, you should see the following output:

```
INFO:__main__:Starting function: example_function
INFO:__main__:Finished function: example_function
Hello, world!
```

This shows that the decorator logged the start and finish of the `example_function` coroutine.
