Django - Caching

What is wrong with this Django cache usage?

cache.set('user_1', {'name': 'Alice'})
user = cache.get('user_1')
print(user['age'])

Acache.set requires a timeout argument

BThe cached dictionary has no 'age' key, causing a KeyError

Ccache.get returns a string, not a dictionary

Dcache.set cannot store dictionaries

Step-by-Step Solution

Solution:

Step 1: Check cached data structure
The cached dictionary only has 'name' key, no 'age'.
Step 2: Analyze print statement
Accessing user['age'] causes KeyError because 'age' key is missing.
Final Answer:
The cached dictionary has no 'age' key, causing a KeyError -> Option B
Quick Check:
Missing dict key causes KeyError [OK]

Quick Trick: Check keys exist before accessing cached dict values [OK]
