LLD - Design — Food Delivery System

Given this snippet:
assigned_agent = None for agent in agents: if agent.status = 'free': assigned_agent = agent return assigned_agent
What is the main error in this code?

AReturning assigned_agent inside the loop

BNot initializing assigned_agent before loop

CUsing assignment operator '=' instead of comparison '==' in if condition

DUsing 'free' instead of 'available' as status

Step-by-Step Solution

Solution:

Step 1: Check the if condition syntax
The condition uses '=' which assigns value instead of '==' which compares values.
Step 2: Understand impact of wrong operator
This causes a syntax error or unintended behavior because '=' cannot be used in conditions.
Final Answer:
Using assignment operator '=' instead of comparison '==' in if condition -> Option C
Quick Check:
Use '==' for comparison, not '=' [OK]

Quick Trick: Use '==' for comparisons in conditions [OK]

Common Mistakes:

Confusing '=' with '==' in if statements
Thinking assigned_agent must be initialized inside loop
Assuming return inside loop is the error
