Python - Custom Exceptions

You want to add multiple custom attributes brand and year to an object car using a dictionary attrs = {"brand": "Toyota", "year": 2020}. Which code correctly adds these attributes?

Afor k, v in attrs.items(): setattr(car, k, v)

Bcar.attrs = attrs

Ccar[attrs.keys()] = attrs.values()

Dsetattr(car, attrs)

Step-by-Step Solution

Solution:

Step 1: Understand how to add multiple attributes from a dictionary
Use a loop to assign each key-value pair as an attribute and value.
Step 2: Evaluate each option
for k, v in attrs.items(): setattr(car, k, v) loops over dictionary items and uses setattr correctly. car.attrs = attrs assigns the whole dictionary as one attribute, not individual attributes. car[attrs.keys()] = attrs.values() uses invalid syntax. setattr(car, attrs) misuses setattr with one argument.
Final Answer:
for k, v in attrs.items(): setattr(car, k, v) -> Option A
Quick Check:
Loop with setattr adds multiple attributes [OK]

Quick Trick: Loop over dict and use setattr to add many attributes [OK]

Common Mistakes:

Assigning dict as one attribute instead of multiple
Using invalid syntax with brackets
Calling setattr with wrong number of arguments
