You want to create a class BankAccount that stores an account holder's name and balance. It should have a method deposit(amount) that adds money to the balance only if the amount is positive. Which code correctly implements this?
class BankAccount():
def __init__(self, name, balance=0):
self.name = name
self.balance = balance
def deposit(self, amount):
if amount > 0:
self.balance += amount correctly sets self.name and self.balance with a default balance of 0.
Step 2: Verify deposit method logic
class BankAccount():
def __init__(self, name, balance=0):
self.name = name
self.balance = balance
def deposit(self, amount):
if amount > 0:
self.balance += amount adds amount to self.balance only if amount > 0, which matches the requirement.
Final Answer:
Correctly implements the class with proper attribute initialization and deposit validation -> Option A
Quick Check:
Check attribute setup and positive amount condition [OK]
Quick Trick:Check attribute setup and validate input in methods [OK]
Common Mistakes:
MISTAKES
Not using self.balance to store balance
Adding amount without checking if positive
Overwriting balance instead of adding
Missing default balance initialization
