In Python DevOps, how do I retry transient errors?

In Python DevOps, it is common to face transient errors when making network calls, database queries, or during API interactions. To handle these transient errors gracefully, you can implement a retry mechanism using libraries such as `retrying` or `tenacity`. Below is an example of how to retry a function call that may raise an exception due to a transient error.

import time import random def transient_error_function(): # Simulating a function that may intermittently fail if random.choice([True, False]): raise Exception("Transient error occurred!") return "Success!" def retry(func, retries=5, delay=1): for i in range(retries): try: return func() except Exception as e: print(f"Attempt {i + 1} failed: {e}") time.sleep(delay) print("All attempts failed.") return None result = retry(transient_error_function) print(result)
