1. class Laptop:

2.     def __init__(self, ram=8):

3.         self.ram = ram

4.  

5.     def set(self, ram=4):

6.         self.ram += ram

7.         return self.ram

What is the expected output of the following code?

laptop = Laptop()

print(laptop.ram)

laptop.set()

print(laptop.ram)

laptop.set(8)

print(laptop.ram)

class BankAccount:

    interest_rate = 0.05

    total_accounts = 0

    def __init__(self, account_number, balance):

        self.account_number = account_number

        self.balance = balance

        BankAccount.total_accounts += 1

 def deposit(self, amount):

        self.balance += amount

    def withdraw(self, amount):

        if amount <= self.balance:

            self.balance -= amount

        else:

            print("Insufficient funds!")

 @classmethod

    def set_interest_rate(cls, rate):

        cls.interest_rate = rate

account1 = BankAccount("123456", 1000)

account2 = BankAccount("987654", 500)

account1.deposit(500)

account2.withdraw(200)

 print(account1.balance)

print(account2.balance)

print(BankAccount.interest_rate)

print(BankAccount.total_accounts)

What will be the output of the code snippet?

1. class Foo:

2.     def __init__(self, bar):

3.         self.bar = bar

4.  

5.     def update(self, bar):

6.         self.bar = bar

7.  

8. foo = Foo(10)

9. foo.update(20)

10. print(foo.bar)

What will the code print when executed?
