Python - Custom Exceptions

Find the mistake in this code that tries to add a custom attribute weight to obj:

class Item:
    pass

obj = Item()
setattr(obj, weight, 50)
print(obj.weight)

Aweight should be a string in setattr

Bobj.weight is not defined

Csetattr requires only two arguments

Dprint statement missing parentheses

Step-by-Step Solution

Solution:

Step 1: Check setattr function parameters
setattr requires the attribute name as a string.
Step 2: Identify the error
The code passes weight without quotes, so Python treats it as a variable which is undefined, causing a NameError.
Final Answer:
weight should be a string in setattr -> Option A
Quick Check:
Attribute name in setattr must be string [OK]

Quick Trick: Always quote attribute names in setattr [OK]
