input: Write a function to simulate a simple ATM machine. The function should include an account class with necessary functions such as depositing, withdrawing, and checking the balance. Additionally, there should be an ATM class to manage multiple accounts, allowing for creation of accounts, depositing, withdrawing, and printing the balance for a specific account.
  
  
  class Account:
      def __init__(self, name, balance):
          self.name = name
          self.balance = balance
  
      def deposit(self, amount):
          self.balance += amount
  
      def withdrawal(self, amount):
          self.balance -= amount
  
  class ATM:
      def __init__(self):
          self.accounts = []
  
      def createAccount(self, name, balance):
          account = Account(name, balance)
          self.accounts.append(account)
  
      def deposit(self, name, amount):
          for account in self.accounts:
              if account.name == name:
                  account.deposit(amount)
  
      def withdrawal(self, name, amount):
          for account in self.accounts:
              if account.name == name:
                  account.withdrawal(amount)
  
      def printBalance(self, name):
          for account in self.accounts:
              if account.name == name:
                  print(name, " Balance: ", account.balance)
  
  assert ATM().createAccount("John", 5000) is None
  assert ATM().deposit("John", 1000) is None
  assert ATM().withdrawal("John", 300) is None
  assert ATM().printBalance("John")
