How to Handle "Max Retries Exceeded" Errors in the Requests Library?

Handling Max Retries Exceeded Error in Requests Library

In a script that attempts to retrieve content from the App Store, an error message is encountered: "Max retries exceeded with URL in requests". This signifies that the requests library has repeatedly failed to connect to the specified URL.

To resolve this issue, it is recommended to incorporate retry-handling features of the requests library. This can be achieved by modifying the script as follows:

import requests
from requests.adapters import HTTPAdapter
from urllib3.util.retry import Retry

session = requests.Session()
retry = Retry(connect=3, backoff_factor=0.5)
adapter = HTTPAdapter(max_retries=retry)
session.mount('http://', adapter)
session.mount('https://', adapter)

url = "https://itunes.apple.com/in/genre/ios-business/id6000?mt=8"
response = session.get(url)

This enhanced script employs a retry strategy:

• Retry(connect=3, backoff_factor=0.5) specifies that the session should retry connecting to the URL up to 3 times, with a half-second delay between each attempt.
• session.mount() associates the retry adapter with both HTTP and HTTPS protocols.

With this implementation, the script will automatically retry the GET request in case of a connection error, significantly improving the robustness of the script.
