Complete the code to check if a service is available by pinging it.
def is_service_available(url): response = ping(url) return response.status_code == [1]
The HTTP status code 200 means the service is available and responded successfully.
Complete the code to retry checking availability if the first ping fails.
def check_with_retry(url, retries): for _ in range(retries): if is_service_available(url): return True return [1]
If all retries fail, the function should return False indicating the service is not available.
Fix the error in the code to handle timeout exceptions during availability check.
def safe_check(url): try: return is_service_available(url) except [1]: return False
TimeoutError is the correct exception to catch when a ping times out.
Fill both blanks to implement exponential backoff in retry logic.
def retry_with_backoff(url, retries): delay = 1 for _ in range(retries): if is_service_available(url): return True time.sleep([1]) delay = delay [2] 2 return False
We sleep for the current delay, then multiply delay by 2 to double it each retry.
Fill all three blanks to create a dictionary comprehension that maps service names to their availability status.
services_status = [1]: safe_check([2]) for [3] in services_list}
The dictionary comprehension uses service_name as the loop variable, service as the key, and calls safe_check on service.
