使用python获取列表附带的数据？

如何解决使用python获取列表附带的数据？

使用 python，我从服务器获得如下列表。但是当我想在“for”循环中返回它时，它给了我一个列表错误。我该如何解决这个问题？

所以总而言之，我想在下面的“for”循环中访问传入的“klines”中的“Open,Close”等数据。

错误

 Traceback (most recent call last):
 File "C:\Users\winuser\Desktop\proje\Python Projects\main.py",line 53,in <module>
 if is_bullish_engulfing(candle=klines,index=i):
 File "C:\Users\winuser\Desktop\proje\Python Projects\main.py",line 21,in is_bullish_engulfing
 current_candle = candle(index)
 TypeError: 'list' object is not callable
