Django - Deployment and Production

Why might this code cause a problem?

import os
ALLOWED_HOSTS = os.getenv('ALLOWED_HOSTS', '').split(',')

Aos.getenv cannot be used with split()

BIf ALLOWED_HOSTS is not set, split will return [''], which is not a valid host

CALLOWED_HOSTS must be a list of integers

Dsplit(',') will remove all hosts

Step-by-Step Solution

Solution:

Step 1: Analyze default empty string split
Splitting empty string by comma returns list with one empty string element.
Step 2: Understand ALLOWED_HOSTS usage
Django expects valid hostnames, empty string is invalid and may cause errors.
Final Answer:
If ALLOWED_HOSTS is not set, split will return [''], which is not a valid host -> Option B
Quick Check:
Empty string split issue = B [OK]

Quick Trick: Empty string split returns [''], not empty list [OK]
