[Solved] What is wrong with this code snippet that handles 429 errors?if response.status_code == 429: retry_after = response.headers.get('Retry-After') if retry_after: sleep(int(retry_after)) retry_request() | Rest API

Rest API - HTTP Status Codes

What is wrong with this code snippet that handles 429 errors?

if response.status_code == 429:
    retry_after = response.headers.get('Retry-After')
    if retry_after:
        sleep(int(retry_after))
    retry_request()

Aretry_request() is called even if retry_after is missing, causing immediate retry

BThe status code check should be 500 instead of 429

Csleep function cannot accept integer arguments

DHeaders cannot be accessed with get() method

Step-by-Step Solution

Solution:

Step 1: Analyze flow when Retry-After header is missing
If retry_after is None, sleep is skipped but retry_request() runs immediately.
Step 2: Understand impact of immediate retry
Immediate retry may cause repeated 429 errors; better to handle missing header properly.
Final Answer:
retry_request() is called even if retry_after is missing, causing immediate retry -> Option A
Quick Check:
Missing Retry-After causes immediate retry, may cause repeated 429 [OK]

Quick Trick: Handle missing Retry-After to avoid immediate retry after 429 [OK]

Common Mistakes:

MISTAKES

Ignoring missing Retry-After header
Assuming sleep can't take int
