Flask - Ecosystem and Patterns

Consider this repository method:

def delete_user(self, user_id):
    user = User.query.get(user_id)
    if user:
        db.session.delete(user)
        db.session.commit()
        return True
    return False

What will delete_user(10) return if user with ID 10 does not exist?

ANone

BTrue

CRaises an exception

DFalse

Step-by-Step Solution

Solution:

Step 1: Analyze method logic for missing user
If User.query.get(user_id) returns None, the if condition fails.
Step 2: Check return value when user not found
Method returns False explicitly in that case.
Final Answer:
False -> Option D
Quick Check:
Missing user returns False from delete_user [OK]

Quick Trick: Returns False if user not found for deletion [OK]
