python - 如何在python中使用循环打印字符串列表中的每个硬币

Question

嗨，我是学习 python 的新手，现在我正在尝试一个代码，我尝试了很多方法，但我无法解决这里是我的代码，此代码仅获取 BTCUSDT VALUES 但我想从字符串列表中获取更多硬币列表，它总是最后打印字符串列表上的值我怎么能一一打印

这是我的画面

BTCUSDT ---开始

最后一个变量：45555.487064533176 最后一个 pmax 45486.47701675686

BTCUSDT ---开始

最后一个变量：45555.487064533176 最后一个 pmax 45486.47701675686

BTCUSDT ---开始

最后一个变量：45555.487064533176 最后一个 pmax 45486.47701675686

我想这样打印

XRPUSDT ——————开始————————</p>

最后一个变量：0.07643779778265652 最后一个 pmax 0.07576949200637356

ETHUSDT ——————开始————————</p>

最后一个变量：0.020887977208516414 最后一个 pmax 0.02071535207020709

BTCUSDT ——————开始————————</p>

最后一个变量：0.0613029012374088 最后一个 pmax 0.06095001184562004

这应该让你开始。

将你的 for 循环移到 while true 循环内

coinlist = ['XRPUSDT', 'ETHUSDT', 'BTCUSDT']
while True:
    for x in coinlist:
        pair = x 
        time.sleep(10)

        try:
            klines = client.get_klines(symbol=pair, interval=interval, limit=limit)
        except Exception as exp:
             msg = f'exception in get_klines {str(exp)}'
             print(msg, flush=True)
             time.sleep(10)
             client = Client(config.API_KEY, config.API_SECRET) 
             continue

        open_time = [int(entry[0]) for entry in klines]
        open_klines = [float(entry[1]) for entry in klines]
        high = [float(entry[2]) for entry in klines]
        low = [float(entry[3]) for entry in klines]
        close = [float(entry[4]) for entry in klines]
