Python - Constructors and Object Initialization

Which of the following is a correct way to define a constructor with a default value for the parameter color set to 'red'?

Adef __init__(self, color): if not color: color='red'

Bdef __init__(self, color): color='red'

Cdef __init__(self, color='red'):

Ddef __init__(self, color=None): color='red'

Step-by-Step Solution

Solution:

Step 1: Understand default parameter syntax
Default values are set directly in the parameter list using assignment, e.g., param=default.
Step 2: Check each option
def __init__(self, color='red'): correctly sets color='red' in the parameter list. Others either assign inside the function incorrectly or don't set default properly.
Final Answer:
def __init__(self, color='red'): -> Option C
Quick Check:
Default value syntax = param=default [OK]

Quick Trick: Set defaults in parameter list, not inside function body [OK]
