def update_transactions(file_path: str, transaction_list: list): """ You are part of a team tasked to create an application that helps bankers by saving their transactions for them. Your job within the project is to implement the feature that actually saves the transactions to the hard drive. The scope of your task is that you will be given a file path to where the data should be written and a list of bank transaction objects to be written to the file. The file will contain a JSON array of transactions that the banker previously saved. The bankers at this bank are silly sometimes and they make duplicate transactions, your function should remove the duplicate transactions in the transaction_list and update the existing transaction list saved in the file with the new transactions. Make sure when you are preforming the update of the new transactions that you overwrite old transactions (transactions that already exist in the file) with duplicate new transactions (transactions that are found in the transaction_list). You will know that a transaction is a duplicate if it has the same ID. In the end the file should contain a JSON list with transaction Objects that have been updated with the new information from the transaction_list. The JSON list should contain no transactions with the same ID. The transaction object referred to here in is outlined below. In actual testing of your code the professors transaction object will be used, which will have all the documented functionality. class Transaction: def __init__(self, id:int, type:str, amount:float): self.id:int = id self.type:str = type self.amount:float = amount def __str__(self): return 'Transaction[%s] %s $%s' (self.id, self.type, self.amount) def __hash__(self): return hash(self.id) def __eq__(self, other): return hasattr(other,'id') and other.id == self.id
