The Blueprint & The Instance
class BankAccount:
def __init__(self, owner: str, initial_balance: float = 0.0):
self.owner = owner
self.balance = initial_balance
def deposit(self, amount: float):
if amount > 0:
self.balance += amount
return self.balance
The class is the architectural blueprint. Each time you call account = BankAccount("Alice", 500), Python instantiates a brand new isolated object in RAM.
Quick Summary
- Classes bundle data attributes and methods together into coherent entities.
- Next, we combine everything into an end-to-end Capstone Project.
