How to Implement Retry with Exponential Backoff and Jitter in Python

This code demonstrates a retry mechanism with exponential backoff and optional full jitter, using a flaky mock network call for testing.

import random
import time


def retry_with_backoff(func, max_attempts=5, base_delay=0.1, jitter=True):
    """
    Retry a function with exponential backoff and optional full jitter.

    for attempt in range(max_attempts):
        try:
            return func()
