Python - Object-Oriented Programming Foundations

How would you modify this procedural code to use an object-oriented approach for managing a bank account?

balance = 1000
def deposit(amount):
    global balance
    balance += amount
def withdraw(amount):
    global balance
    balance -= amount

deposit(500)
withdraw(200)
print(balance)

AKeep functions as is but add a class wrapper

BUse global variables inside a class without methods

CDefine deposit and withdraw as static methods without balance

DCreate a BankAccount class with balance attribute and deposit, withdraw methods

Step-by-Step Solution

Solution:

Step 1: Understand procedural code with global balance
The code uses a global variable and functions to modify it, which is procedural style.
Step 2: Convert to OOP by encapsulating balance and methods
Creating a class with balance as an attribute and deposit/withdraw as methods encapsulates data and behavior properly.
Final Answer:
Create a BankAccount class with balance attribute and deposit, withdraw methods -> Option D
Quick Check:
OOP encapsulates state and behavior in objects [OK]

Quick Trick: Encapsulate data and functions inside a class [OK]

Common Mistakes:

MISTAKES

Using global variables inside classes
Making methods static without state
Not encapsulating balance properly
