Consider the following code snippet using Tkinter:

from tkinter import Tk, Canvas

 root = Tk()

 canvas = Canvas(root, width=200, height=200)

canvas.pack()

 canvas.create_line(0, 0, 200, 200)

 root.mainloop()

What does this script do when executed?

Consider the following code snippet:

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?
