Retryer Function Implementation

Design a retryer function that takes an asynchronous function and a maximum number of retries. The retry delay should grow exponentially (e.g., 2 seconds, 4 seconds, 8 seconds, etc.). If the asynchronous function succeeds within the maximum retries, return the result; if it fails after the maximum retries, throw an error. Input func: an asynchronous function to retry, with no parameters. max_retries: an integer specifying the maximum number of retries. Output Returns the result of the asynchronous function or throws an error. Example async def my_async_function(): # Simulate a potentially failing async call result = await retryer(my_async_function, 3) Constraints Assume each call to the async function is independent and has no global state. Exponential backoff should wait for a maximum of 16 seconds, use await asyncio.sleep() to simulate wait time. Example Input async def test_func1(): raise Exception("Failure") await retryer(test_func1, 3)
