Пример использования:

account = BankAccount() account.deposit(100) print(account.balance) # Output: 100

account.deposit([50, 75]) print(account.balance) # Output: 225

account.deposit(25, "ATM deposit") print(account.balance) # Output: 250 print(account.transaction_history) # Output: [(25, 'ATM deposit')]
