Python - Constructors and Object Initialization

You want to create a class Employee where the constructor has default values for department as 'Sales' and salary as 50000. You also want to allow creating an employee with just a name. Which constructor definition is correct?

Adef __init__(self, name, department='Sales', salary=50000):

Bdef __init__(self, department='Sales', salary=50000, name):

Cdef __init__(self, name='Unknown', department='Sales', salary=50000):

Ddef __init__(self, name, department, salary=50000='Sales'):

Step-by-Step Solution

Solution:

Step 1: Identify correct parameter order and defaults
Name is required, so it must come first without default. department and salary have defaults and come after.
Step 2: Check each option
def __init__(self, name, department='Sales', salary=50000): correctly places name first, then default parameters. def __init__(self, department='Sales', salary=50000, name): places name last (invalid). def __init__(self, name='Unknown', department='Sales', salary=50000): gives name a default which is allowed but changes requirement. def __init__(self, name, department, salary=50000='Sales'): has invalid syntax.
Final Answer:
def __init__(self, name, department='Sales', salary=50000): -> Option A
Quick Check:
Required params first, defaults last [OK]

Quick Trick: Put required params before default ones [OK]

Common Mistakes:

MISTAKES

Placing required params after defaults
Invalid default assignment syntax
Giving required params default values unintentionally
