Build a URL Shortener Client with Python
A Python class that shortens long URLs and resolves short codes using a REST API built with requests.
import json
import sys
import requests
class URLShortenerClient:
def __init__(self, base_url="http://tinyurl.com"):
self.base_url = base_url
def shorten_url(self, long_url):
payload = {"url": long_url}
headers = {"Content-Type": "application/json"}
response = requests.post(f"{…Exponential Backoff with Jitter for Cloud API Calls in Python
A Python snippet demonstrating exponential backoff with jitter for retrying transient cloud API failures, using a simulated client that has a configurable success rate.
import random
import time
def exponential_backoff_with_jitter(retries=5, base_delay=0.5, max_delay=4.0, jitter_factor=0.3):
for attempt in range(1, retries + 1):
delay = min(max_delay, base_delay * (2 ** (attempt - 1)))
jitter = delay * random.uniform(-jitter_factor, jitter_factor)
