How can I implement retry logic in my application?

How can I implement retry logic in my application?

You can implement retry logic by using a loop that attempts an operation multiple times before failing. Would you like a code example?

Yes, please provide a code example for a network request.

Here's a simple example in Python using the requests library:

import requests
import time

def make_request(url, retries=3, delay=2):
    for i in range(retries):
        try:
            response = requests.get(url)
            response.raise_for_status()  # Raise an error for bad responses
            return response.json()
        except requests.exceptions.RequestException as e:
            print(f'Attempt {i + 1} failed: {e}')
            time.sleep(delay)
    return None  # Return None if all attempts fail

This will try to fetch the URL up to 3 times with a 2-second delay between attempts.

What if I want to implement exponential backoff?

You can modify the delay to increase exponentially with each retry. Here's an updated version:

def make_request(url, retries=3):
    for i in range(retries):
        try:
            response = requests.get(url)
            response.raise_for_status()
            return response.json()
        except requests.exceptions.RequestException as e:
            delay = 2 ** i  # Exponential backoff
            print(f'Attempt {i + 1} failed: {e}. Retrying in {delay} seconds...')
            time.sleep(delay)
    return None

Thanks! This is really helpful.
