创建列表时遇到问题

Question

我制作了一个股票筛选器，可以提供符合我标准的股票的技术指标，最后，我希望它能打印一份符合我标准的简明股票清单。我尝试使用追加功能，但它只打印一只股票，相反，我希望它打印每只打印的股票的代码，例如 'mmm',...

当前输出如下所示。嗯尾随 P/E：17.61 Return 股权：54.34% 收入：32.35B 季度收入增长：-5.00%

def scrape(stock_list, interested, technicals):
    for each_stock in stock_list:
        technicals = scrape_yahoo(each_stock)
        condition_1 = float(technicals.get('Return on Equity',0).replace('%','').replace('N/A','-100')) > 25
        condition_2 = float(technicals.get('Trailing P/E',0).replace('N/A','')) > 15
        condition_3 = float(technicals.get('Price/Book (mrq)',0)) <15
        if (condition_1 and condition_2)==True:
            print(each_stock)
            SuggestedStocks = []
            SuggestedStocks.append(each_stock)  
            for ind in interested: 

                print(ind + ": "+ technicals[ind])         
            print("------")
            time.sleep(1)                                                    # Use delay to avoid getting flagged as bot
    #return technicals
    print(SuggestedStocks)


def main():

    stock_list = ['MMM', 'ABT', 'ABBV', 'ABMD', 'ACN', 'ATVI', 'ADBE', 'AMD']
    interested = ['Trailing P/E', 'Return on Equity', 'Revenue', 'Quarterly Revenue Growth']
    technicals = {}

    tech = scrape(stock_list, interested, technicals)
    print(tech)
main()

它只打印符合我的 criteria:ADBE 的最后一只股票的代码。

Answer 1

这是因为你在每次循环中都重置了建议股票SuggestedStocks = []你应该在循环外初始化它。
