从读文件创建对象

Question

我试图使用文件中的数据提取并使用它创建对象。

的数据的一个例子：ACB，20170327,0.058,0.058,0.058,0.058,175116

这是数据的格式： stock_code，日期，opening_price，HIGH_PRICE，LOW_PRICE，closing_price，体积

我试图创建一个对象是这样的：

stock_code = TradingData（日期，opening_price，HIGH_PRICE，LOW_PRICE，closing_price，体积比）

这是我到目前为止

Answer 1

for stock in file: 
    parse_trading_data(stock) 

def parse_trading_data(stock): 
    str_arr = stock.split(',') 
    data = { 
       "date": str_arr[0], 

        ... 

      } 
    return TradingData(data) 

像这样的事情？
