[Solved] Find the error in this retry logic snippet:def fetch_data(): retries = 3 while retries > 0: response = api_call() if response.status_code == 200: return response.... | Rest API

Rest API - Webhooks and Events

Find the error in this retry logic snippet:

def fetch_data():
    retries = 3
    while retries > 0:
        response = api_call()
        if response.status_code == 200:
            return response.data
        retries -= 1
    return None
    retries -= 1

AThe last line decreases retries after return, unreachable code

BMissing sleep between retries

CNo check for network exceptions

DShould use for loop instead of while

Step-by-Step Solution

Solution:

Step 1: Review code flow
The last line retries -= 1 is after return None, so it never runs.
Step 2: Identify unreachable code problem
Code after return is unreachable and unnecessary, indicating a logic error.
Final Answer:
The last line decreases retries after return, unreachable code -> Option A
Quick Check:
Code after return is unreachable [OK]

Quick Trick: Code after return is never executed [OK]

Common Mistakes:

MISTAKES

Ignoring unreachable code warnings
Forgetting to add wait between retries
Not handling exceptions
