我希望我的代码仅在结果与之前的结果不同且不再相同时才打印

Question

每当我运行代码时，此代码都会打印它从 api_url 获取的最新结果，但我希望它检查结果是否与上次相同，然后不打印它。

注意：这是我第一次在这里提问，所以如果我在问题中犯了任何错误，请原谅。

 api_url= "https://api.bscscan.com/api? module=account&action=tokentx&contractaddress=smartcontract&address=" + person1["address"] + \
    "&startblock=10290674&endblock=999999999&page=1&offset=1&sort=desc&apikey=APIKEY"

 response = requests.get(api_url)
 address_content = response.json()
 result = address_content.get("result")  

 for n, transaction in enumerate(result):
    block = transaction.get("blockNumber")
    hash = transaction.get("hash")
    tx_from = transaction.get("from")
    tx_to = transaction.get("to")
    value = transaction.get("value")
    confirmations = transaction.get("confirmations")

    coin_value = Decimal(value)/1000000000000000000

    coin_value = int(value)/1000000000
    print("COIN", coin_value)
    print("\n")
    
    if tx_to in (tx_sell, tx_sell2):
        print("sell")
    elif tx_from in (tx_sell, tx_sell2):
        print("buy")

将结果存储在一个文件中：

myfile = open(“result.txt”,’w’)

myfile.write(str(result))
